I used to spend day and night in the PC working to figure out bugs and errors all over the source codes, Believe it or not I`ve the very tight schedule hence I`ve also started learning other courses in my free time. So, please do guys suggest me what am i have to do (to keep myself healthy) in between of working during break time. PS: I used to work with the computer over 8 hours a day, i get 15 mins break each 2-3 hours. so what should i do, go for a walk or some minor exercise to be done from sitting??
