I am software programmer and I do lots of research like software/database architecture most of the time. I recently got comment from my friends that I am looking older than my age. I am 28 and I am said to look around 38. I came home and had a look in the mirror and saw that I have receding hair lines , big beard and unhealthy face. I don't exercise much. I am doing my MBA and hold a full time job where I have lot of responsibility.
My college are ending in a month and I will have more time. How can I revive my health and youth? Is there any suggestion to remain healthy internally and externally?
