Well when you got Co workers complaining about pains in their knees and backs and they are visibly overweight, I can't help reply with eat less and move more. I usually get get 'but it hurts when I use it', people are weird.
I'm sure it's other people that make you sick and not just temperature. I work outside, can't remember the last time i was actually sick (still use my sick days though😁 I ain't no hero).
