I work sometimes at a hotel. I once overheard a man talking about getting the youth more interested in their heart health. (I googled him because I heard his name being used by the waiter) Turns out he's a super respected heart surgeon from another city and he's nearing his 80s! (Local newspaper wished him happy birthday) he looked younger by like fifteen years and didn't slouch as he walked. I didn't speak to him because I didn't want to depress him with a field report of today's youth (I'm 22).
