The body is a pretty amazing machine.It adapts to new environments. For example, in equatorial regions we develop more pigment to prevent burning. And in arctic regions we retain more bodyfat for insulation against cold weather.It responds quickly and measurably to stimuli. For example, step on a tack and you will reflexively flex the knee and or hip to pull away from the source of the pain. Or if you cause damage to the soft tissues of the body, which help to maintain strutural integrity, we will get an inflammatory response to provide more stability to the injured body part.For everything we subject our bodies to there is a reaction. Sometimes the reaction is obvious and external which allows us to take notice and make the connection. Falling asleep in the hot sun on vacation may result in a sunburn which is easy for us to recognize and connect the dots as to why we got burned.Other reactions in our body are harder to perceive.They may not be as immediate.Drinking 2 cans of soda a day as a young person may eventually lay the foundation for future diabetes issues. But at the time it is difficult to recognize the damage we are doing.I guess it's kind of like being a baby.We are not able to communicate our needs except through crying. And unless something is painful, such as a dirty diaper or hunger pangs, we may not cry at all, giving the impression that everything is alright.But absence of pain doesn't mean everything is alright.We can be putting stress and doing damage to our tissues and organs without even realizing it.How can this happen?Well as long as we can 'get away' with a lifestyle or habit there is no reason to change it, is there?However when we discover there is a problem we always...
