The only thing I proselytize is stretching. Especially since all my peers are addicted to computer and phone. I see a great deal of back and neck pain in the future. Please, even if you find it boring, cringe, or annoying, stretch. Do whatever you can to make this part of your daily routine. If not, I guarantee you’ll spend more than half your life in physical pain. And, with all the potential sources of existential pain on offer, why not do your best to mitigate your inevitable physical demise as much as possible.
