Is being in nature good for lifespan?

I read white tea has ten times as much nutrition as an organic orange but when I drank white tea, I gained 10 pounds so I quit my white tea, and my mom says farmers always live short lives in China because they wear out their bodies by doing too much manual labour and I knew a woman who worked 14 hour days that was obese and her job was physical labour and she looked flabby and not muscular, so I think exercise is not the only way to lose weight, there is a much easier answer.
