In 2017, i lost weight by running. i would run every day for an hour? and i would purposely and heavily jostle my face and body. my face changed and is not pretty as before. do i have saggy cheeks due to the jostling? suggests change notbc weight los?

Probably any change in your appearance has nothing to do with running, and of course exercising and physical conditioning are healthy and good. Everybody's face changes as they grow older: nobody's face is the same at age 20 as at 17. That's life. This probably is not a cause for worry. But discuss with your doctor if you remain concerned. Good luck.
