After a long contribution to maintaining good health let me drop this .
It is very important to balance your job time and resting time, the body is not a machine ,it needs rest ,even a machine gets tired.
•Avoid overthinking,thinking kills faster than stress.
•Stop or reduce some harmful habits you cant do without, excess consumption of alcohol ,smoking, constant overfeeding, Addiction to pornography, masturbation stop or limit it.
•Avoid totally or limit excess use of drug substances .
•Avoid holding farts or urine for the long it harmful to the body .
•Avoiding dipping your hand in your mouth without wash or using to teeth to cut your nails .
•Avoid using your teeth as crown cock cover opener.
•Watch your hands before and after touchin your private parts.
It is easy to say avoid overthinking but its very hard, also it is easy to say exercise but it's real real hard thing to do with consistency.
But I think one should practice doing it. Try hard if you have trouble with it. And everything will be okie.
