The secret to a healthy life is:
1. Eat only real food. Never put atificial crap in your mouth. Real food: meat, eggs, fish, diery...
2. Be physically active. Set your minimal activity level and hit it every day. Walk at least 10000 steps. Lift weights.
3. Communicate. Be around and talk to people. Meet new people.
Incorporate these things into your life, make them interesting to you, and enjoy your new healthy life.
