Advice: It does not matter how old you are, think about the damage you are doing to the 1 body that you have.
Some damage is irreparable, and it's never too early to take precautions ( eyes, knees, back ).
There's 168 hours in 1 week: Spend 1 of those hours outside.
Turn off the computer and the TV. Don't touch your phone.
And, see if you can spend 1 continuous hour without an electronic device.
The fresh air, and lack of electronics, will recharge YOUR batteries,
and leave you feeling refreshed.
It doesn't matter if you sit, walk, stare at the trees, or just close your eyes…
Take some time for yourself this week.
