"YEAH, BUT I WANT TO LIVE FOREVER. ISN'T YOGA SUPPOSED TO TEACH YOU HOW TO DO THAT?"
"Sorry, dude, you're going to die. But you should do your yoga anyway, because you'll feel a lot better when you're done. Practice isn't going to keep you alive forever but it might help you calm your mind and get rid of some of those fears. That alone makes it worth the time."
"When you practice yoga, you're really practicing living and dying, learning how to deal with the reality of impermanence. Also, sometimes, you stand on your head."
