Nice to see you started a health thread, Neeraj. I found some good advice I hadn't heard of before. Moreover, I consider this an important matter - and, unfortunately, an underrated one - and I will try to give a small piece of advice as well - which is mainly about stress relief.

Apart from walking, stretching also helps relieve stress and feel better - our joints need it, too. I do it and find great pleasure in it as well.
If you have a small aquarium, try watching your fish for a few minutes every day. It is one of the most relaxing and soothing sights in the world.
Cuddling furry animals like cats and little dogs can reduce stress in a big amount. Actually, cats are used in some hospitals and have a big success in soothing down the patients before a surgery or even on a daily basis.

Just some thoughts. If anyone finds them helpful, then I'll be happy.
