A few months ago I read an article about an eighty year old man who is good shape. He spoke at length about how he keeps fit and when asked about his secret he basically said that he walks everyone. No buses and no cabs. His two feet serve as his primary mode of transportation. I can respect this since I love to walk everywhere it is a very rare occurrence that I use public transport.
It is both a matter of saving money and also keeping myself physically fit. Sure there are times when I am tired from all of the walking I do but I keep hearing from people that I have lost a lot of weight. I don't notice it as much because I have always had an interesting way of looking at myself. When I was younger I always saw myself as older and as I get older I now see myself as younger. Maybe that is the key to staying young.
