Do you believe people who walk or exercise are happier then people who avoid physical exercise?

I believe one of the reasons my cousin and uncle have such successful careers is their dedication to exercise and working out. They are intelligent but if they did not look good, they may not have had the same opportunities that they were given. My uncle when wanting to buy his medical office for his career, offered less money then a competing guy who also wanted to buy the office, but my uncle told them he wanted to save people's lives and they would be doing him a huge favour if they sold it to him as it would launch his career, so they sold the office to my uncle even though his offer on the property was lower then his competitor who also made an offer on the property. He's been working there around 30 years now and he's had clients thousands of times richer then the rich people you know in your school or church.
