history: I love being physical fit and exercising. I try to keep my body toned. That's good. Physical exercise enhances or maintains fitness and helps overall health. I agree. It helps you be mentally fit and self confidence and a sense of happiness. I love lifting weights. Human society has placed great value on the beauty of the human body. I meant love lifting weights. Although not necessarily fair it's true good looks go a long way. Well, before the Industrial Revolution, being fit meant you could get through the day without too much fatigue. Really interesting. That is cool to know. Carrying out today's activities have a different meaning to me.
knowledge: However, with automation and changes in lifestyles ''physical fitness'' is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
