@steffi 51m here. CABGx3 in '16.
After a doc visit: rope a friend in. Almost anything is possible when you are playing with a friend!
Walk, ride a bike, lift light things, kick a ball around, throw a ball around, Hit a ball around, chase fireflies (run,) take selfies at the top of hills, then mountains and bore your neighbors showing them.
Food? Eat as minimally processed as possible. Lots of fruit/veg, grains. Enjoy non-sugar drinks, spices, and try to eat with others as much as possible. Invite friends over, and go to their homes!
It's unlikely we will have more than another 50 years, so let's enjoy the ones we have left!
