I hit 70 this year & I feel better than when I moved 16 years ago, alone (with my dog) to my little farm across the country from where I lived all my life to a town whete I knew no one. I take care of most everything on my farm. Bought a chain saw for myself last Christmas & have spent this year clearing brush to add to the clearing I hired done last summer that required a small bull dozer. I mow the acres of fields myself. Takes longer being one person but it is an awesone way to stay young. I don't take any meds because I have bad side effects to even antibiotics. I figure I am like the ever ready bunny.....I go & go till my battery runs out. I am ok with that & too busy enjoying my life to worry. Being surrounded by nature gives one a whole different perspective on live. Came here from Los Angeles & I would NEVER live in a city ever again
