Longevity

There's somewhat of an open secret on how to improve your longevity significantly. The main way is by having a goal. As long as you have a goal that you aren't willing to die before achieving, you'll significantly increase your life expectancy.

Another way to improve your longevity is to continue doing things that might be considered "hard" even as you age.

If you start letting others take care of everything, your body will rapidly deteriorate.

Things that were "hard" a month ago might become impossible by next week.
