Body Changes Retirement is not the only thing that happens at a certain time of life. Our body also does some interesting – and not always helpful – things too. But once we understand what aging does to our body, we can take action to reduce its impact and make the most of our after-work life. With age – Our skin become looser and drier Our muscles become smaller and weaker Our metabolic rate – the speed at which our body burns calories – becomes slower, so we can more easily gain weight Our eyesight becomes less sharp – though I think God is really kind about that because we can’t see our wrinkles so easily Our memory can fail us in a variety of ways None of this can be avoided. But there are ways to slow it down, if we make the lifestyle changes and adopt healthy habits that will keep us youthful. And even if it might have been better to take preventative action a decade or two sooner, it is never too late to begin. The key things are exercise and weight loss.
