There is no doubt that as you get older, it becomes more and more difficult to keep yourself in perfect shape. Somewhere the weight has gone up, the muscles have become flabby. But still, I'm not ready to give up. I go to the gym, walk and ride a bike every day. I use smart Vont scales ordered through amazon to monitor my body fat balance. Of course, these aren't lab results, but they help me determine the direction I need to go in. Add more exercise or stay at my chosen level. I like that I can keep my BMI close to 22%.
