I got frequently sick because I had a shit diet. I would basically not eat enough for the kind of activities I was doing.
Getting sick almost always hit me like a truck and I have a funny story about it.
I've always been told that I'm exaggerating how sick I was by everyone in my family (hint: the women mostly. my dad always took it seriously)
and this one time I felt extremely bad and everyone was telling me oh it's nothing this that whatever, until I told my dad we had to go to the hospital.
turns out my appendix was about to rupture
suddenly after that everyone got an idea that maybe I actually can wage the pain level I'm at
and yes when I got COVID I was bedridden for 3-5 days but so was my entire family
