What is your own formula for keeping good health?

My formula is very simple only. I always try to eat home-cooked food. My mother says it is best. I avoid too much oily and spicy things. Every morning, I go for a walk for 30-40 minutes. It makes me feel fresh. I also do some basic yoga and breathing. This helps with the body's flexibility. I drink plenty of water all day. The main thing is to get proper sleep, at least 7 hours. And try not to take too much tension. These small daily habits are my secret for good health.
