    from a purely biological point of view, two hands (or four limbs) were enough to survive. it is entirely possible that in our distant past, mutants, able to grow four hands (or 6 limbs), were born. In that scenario, selective pressures would have eliminated such individuals, resulting in what we are today.

    This concept essentially applies to any part of our body. why do we not have 2 heads, or three fingers? our current bodyplan simply represents the most efficient means to thrive in our (past) environments

Fitness training is in for your body goals. Nutrition hubs offer you dietary guides for a healthier lifestyle. You go through self-discipline. No cheats. Everybody wants this as they say “Health is wealth.”
While some are on a strict diet, there are also a number of people whose imagination is as rich the foods they eat every day; imagining themselves in a Scarlet Johansson or a Channing Tatum body in front of the vanity mirror. Ironically, at the end of the day, they flood your feeds with #foodporn #foodgasm and complain over their fats piling up. Have a well-balanced diet and activities instead of a rich imagination without an act. Health is to fitness as fitness is to health. They’re two inseparable things that go well with lifestyle.
