People who look fit and feel well can be in terrible cardiovascular health without realising.
Also, the damage that accumulates while you're feeling fine is irreversible.

Reminds me of my doctor (who's a friend) telling me of a patient who's husband just dropped dead at 50 something. "He was in such a great health " the lady said, "never ever went to see a doctor!"
Well, there might be a funking correlation right there.
Care to elaborate?
First part: Lot of people who workout barely do any cardio, there's even this belief that cardio will make you lose muscle mass, but unless you're an athlete it's completely ridiculous to worry about that. The people that are in the best all around shape are very often not the ones who look the most fit or that are the strongest. We need fat on our body as an energy reserve, just doing cardio doesn't build enough muscle mass to slow down the effects of aging on it, just building muscle mass without doing cardio means your heart might be the weakest link in your body...
Second part: Not sure, I guess they mean that it takes a while to not feel fine from the damage accumulated from not taking care of yourself and by the time you don't feel fine anymore most of the damage is irreversible... I guess it's true for many things... If you damaged your knees from being overweight for a long time, suddenly losing weight won't make the cartilage reappear for example...
Now you have me paranoid. I am pretty fit and active, and I certainly have plenty of fat on my body as an energy reserve. It's 90% cardio though. My weight training is just roughhousing with two kids climbing all over me basically.
I have never personally placed value on bulking up. My legs are already huge from running/cycling and while my arms are not especially big, they're wiry and plenty strong enough for my normal needs.
Do I really need to think about weight training as well? To reiterate: I don't care about looking like Arnold Schwarzenegger, I just want to be pretty fit and active in my 80's for future hypothetical grandkids.
It's all a balancing act, without changing the activities you do you start losing muscle mass in your thirties. The good news with kids is that most love climbing so that can be a great activity to do with them if it's available around where you live and you don't like weight training.
If you already run and ride you're ahead of most, so don't get too paranoid about it!

Meh, this is not a great take. Resistance training is unambigiously great for the heart, nearly as good as aerobic in isolation. A runner who doesn't do resistance training is in roughly the same position as a weight lifter who doesn't run (both seem to reduce risk by 30-70%)
However, aerobic and resistance together seem to be better than either in isolation.
Additionally, resistance training has a number of additional health benefits outside of cardiovascular health, to the point that I would say that doing resistance training in isolation is functionally a better use of time for your health than aerobic exercise.
Ideally, you should do both.
The only time this is not true really is when the individual is taking PEDs which do increase risk of heart failure.

I recently had a heart attack at 41.
I'm not obese and look and feel fit and well. I cycle regularly and don't eat a lot of refined foods (particularly carbs). I didn't think I was particularly "fit" but nor did I think I was at risk of heart disease. About 2 months before my heart attack I rode my mountain bike 150km over rough, remote, Australian terrain in 4 days.
Yes I have high cholesterol, have been a smoker in the past, and a family history of type 2 diabetes - I knew these things were problematic in some vague sense but no idea how they relate to cardio problems. Also information is very complex - there's a lot of misinformation about cholesterol for example and as someone who is not a cardiologist it's hard to know what it really means.
Basically, shit builds up in your arteries over time. You feel 100% fine until something clogs up. It's not a progressive deterioration of feeling unwell and not doing anything about it, it's fine > fine > fine > fine > dead. There's no therapy to clean the shit out of your arteries, it doesn't get reduced over time. Once an artery clogs the options are inserting an internal scaffold, or taking an artery from somewhere else to build a by-pass.
I kind of got unlucky but also lucky - unlucky with all of these contributing (mostly hereditory) factors - lucky in that my arteries are generally ok - there was only one bad spot which could be remedied with an internal scaffold. Imagine feeling fine through to your 60s and then finding that your arteries are generally fucked with many trouble spots.
I shouldn't be alarmist in that I don't think this is a problem for people generally, but in terms of things I recently learned that everyone should know - I think cardiovascular health is definitely on that list.
Suffice to say I recently learned that feeling fine does not necessarily mean that you are fine.
It really can be a silent killer. I know someone who's mother was in her 50s. She was thin, fit, active and seemingly healthy. She would enter in races and such, to give you an idea of how fit she was compared to others in their 50s. Now, she wasn't exactly a professional runner or anything, but certainly did it more than others at her age.
Well she died of a heart attack a few months ago during a workout...
Thank you for bringing this up. I'm a nurse on a cardiovascular progressive care unit, and we get a handful of young people (40-50s) who come in with "no prior history" having heart attacks or borderline heart attacks.
One of the things I'd note is that most of them have high blood pressure that they didn't know about. High blood pressure doesn't feel bad, so they never felt a need to see a doctor. But it is silently damaging arteries, particularly the delicate ones in your heart, kidneys, and brain.
The only way to know if you are developing high blood pressure is to get it checked regularly. Get an automatic blood pressure cuff for your house, or go to your primary care physician once a year. And when they tell you that 140/90 is putting you at higher risk of heart attack, take them seriously.

Yeah, you can't just say something like that then not elaborate.
Birds construct a nest in which to incubate eggs and raise chicks, the nest is abandoned after just a few months. For the rest of the year the bird won't have a nest.
Well, then my answer to OP is also 'Birds don't live in nests.'
Repairing your bike is easy and checking the important parts every couple of months makes riding it a lot better.
Same thing with cars. Checking tires increases milage, checking fluids can save you a ton of money, changing oil isn't hard and takes basic tools.
To clarify, just checking these things doesn't do anything. Checking them, knowing what's wrong, and then taking action is what saves you a ton of money.

Life became easier when I learned knots and sewing
Be careful around popcorn kernels when youโve got an old filling.
Cooking.
I had always been afraid of it. Now, I love it.
My biggest advice to anyone who wants to start cooking or is too intimidated to cook: just start doing it. Find a recipe that's simple, follow it to a T and then just keep doing it. You will suck at first, but that's step 1 of any skill. If you cook every night, by month 1 or 2, you'll be significantly better and can expand. Also, whatever time the recipe you looked up says, 1.5 times or double it (especially anything involving cooking onions). You don't have the skills to get it down to that time, and most skip prep work to make it a "quick" recipe.
An important skill to have when cooking is: it doesn't cook faster when you turn the heat up.
I see so many people try this, it's not how it works.
And don't be discouraged when it never turns out, because a lot of recipes these days are written by influencers that aren't giving you the proper measurements, so it'll never actually work out.
When you find a person that actually uploads some proper recipes, follow them, and continue to make their other recipes.
You'll never learn if you're set up for failure and think it's your fault.

Economics. I never understood it that well having taken two years of high school classes for law and government, then watched a single Economics Explained video and understood so much that I hadn't understood before.
Economics is one of those subjects where the more you undestand the less you feel like you do. I can barely wrap my mind around index funds and compounding interests.
On the plus side, they feel fictional because they're completely made up.
Just because something is abstract doesn't mean that it is fictional. Money is made up and essentially an arbitrary placeholder for the general concept of value, but money isn't a required part of an economic system. Economic interactions would occur whether or not a particular society has money (e.g. a pure barter system is still an economy).

Shitty arsed boring teachers probs Vs a well worded video
When adjusting bicycle derailleur, use the second smallest and second largest cogs to adjust the shifting and the biggest and smallest ones only to adjust the limit screws. There's no point adjusting the cable tension if your derailleur is resting against the limit screw.
Thank you! I need to adjust mine, this is great advice!
Advanced tip is to remove the derailleur hanger and see against a flat surface wether it's straight or not. If not, and you don't have the calibration tool then just clamp it on a vice and use hammer/pliers/crecent wrench to bend it back straight. It's not going to be perfect but since it's already bent you're probably not going to make it worse either.

That you can think of an average as the center of mass of a dataset. Similarly, that you can think of a standard deviation as the center of mass of the distances between each point and the average.

Its pretty easy to make your own soda. 1 tsp Sodium or Potassium bicarbonate, 1tsp citric acid OR ~3-4 tablespoons vinegar, flavoring (fruit juice or drink mix + sweetener to taste) and 2-4 cups of water in a bottle with 3-4 inches of room to prevent it from exploding before you cap it. Throw it in the fridge or use cold water.
Alternatively you can make fermented soda using yeast but this isnt something I normally do since I am purposefully using potassium bicarbonate as the bicarbonate source to pressurize the soda. (More potassium in my diet)
The main advantage of making soda yourself is you can make it any flavor you want. You arent really limited by what flavor of soda you can buy.

I realized last night while doing a puzzle with friends that I can just take a picture of the puzzle box. That way we aren't fighting over the box, and I can zoom in and rotate the picture anyway I need to.
I'm not sure this is a brilliant discovery or I am just a bit slow.
