After retirement

I have been looking for my life-work after retirement. Some people want to be free from any restriction ,without any routine job and simply to live on a pension. What should I do in my remaining life? The crucial condition is to keep myself healthy both in mind and body. It might be important to be wealthy enough.However, buisiness is stressful.I finally came to the end ; it is making a contribution to society through education by English teaching at school.
