People have all sorts of perceptions about keeping fit. but one thing I can tell you is keeping fit is essential for a healthy life style. As we focus to live life to the fullest of the little time we have on earth, I believe having a daily work out plan and eating healthy helps your body not to age. As we grow, our metabolism decreases, therefore the metabolic rate decrease almost linearly with age. This is proven facts. Fat tissues increases with age and accumulates in almost every part of the body especially the abdomen. We can actually do something about it by incorporating alot of physiological functions such as a work out routine and avoiding bad habits like smoking and drinking. This essentially brings positive change to our lifestyle and equally delays aging in addition to having a healthy balanced diet. It is one thing knowing it, and another thing to actually do it. but doing it takes motivation , discipline, focus and hard work.
