So I got a smartwatch (Galaxy Watch 6) off the Samsung EPP.
It registered very high stress levels during social events and... work meetings including those where I don't have to speak much, and medium/low while driving, and it barely registered any reading when chatting about anything and everything to my wife.
In reality I feel the complete opposite, idgaf much about the social event (only there because I drove my wife there), the work meeting is just a regular design walkthrough/planning/standup/etc, nothing serious, and I still feel a little bit nervous driving lol.
