I am 63 years old.I have threw thick and thin worked out since I was 13.I know its hard for anyone to start a habit late in life.But it makes a big difference.I had to go to the va near where I live now.Once I was there I surrounded by people my age who looked 99years old.They don't work out white a sheet.If thats aging gacefully than you can have it.Believe me I have not lead the perfect life but I think you such worry more about your body then if your car is dirty or not.
