Excercise absolutely makes you age better. Actually, it seems that in order to have a decrease in all-mortality you need to exercise quite a lot (at least 1.5hrs a day.. for the rest of your life).

Aerobic exercise of course means more caloric expenditure, which you should totally compensate, but that's not hard for regular folks who train, only for extreme athletes

Assuming a 80 year lifespan, that would amount to 5 years exercising. So you need to weigh that up again...

If you really like swimming / football / cricket / basketball / hiking / climbing / whatever then it sounds like a great trade-off. More fun in exchange for better health is a deal anyone would take.

If you hate exercising you won't do it for 1.5h/day anyway.

If you enjoy exercising, you get to do something you like, which on top of that increases your (healthy) lifespan. Win win.

This is why it’s best to find a form of exercise you enjoy
