It certainly has a blind side to that which can not be empirically measured.
science and other "objective" activities are done by people and funded by people with agendas ... so all these activities have a "side"
This comment has a valid point because of the pharmacy's. however, even if they are trying to sell something, can we just ignore the facts?
Here is some real facts.
Sarcopenia literally means "lack of flesh." It's a condition of age-associated muscle degeneration that becomes more common in people over the age of 50.
After middle age, adults lose 3% of their muscle strength every year, on average. This limits their ability to perform many routine activities.
Unfortunately, sarcopenia also shortens life expectancy in those it affects, compared to individuals with normal muscle strength.
Sarcopenia is caused by an imbalance between signals for muscle cell growth and signals for teardown. Cell growth processes are called "anabolism," and cell teardown processes are called "catabolism"
For example, growth hormones act with protein-destroying enzymes to keep muscle steady through a cycle of growth, stress or injury, destruction and then healing.
This cycle is always occurring, and when things are in balance, muscle keeps its strength over time.
However, during aging, the body becomes resistant to the normal growth signals, tipping the balance toward catabolism and muscle loss.
Immobility, Including a Sedentary Lifestyle
Disuse of muscle is one of the strongest triggers of sarcopenia, leading to faster muscle loss and increasing weakness.
Bed rest or immobilization after an injury or illness leads to rapid loss of muscle.
Although less dramatic, two to three weeks of decreased walking and other regular activity is also enough to decrease muscle mass and strength.
Periods of decreased activity can become a vicious cycle. Muscle strength decreases, resulting in greater fatigue and making it more difficult to return to normal activity.
O.k. I think that everyone gets the picture?
I was watching a taichi master "bragging" how he has no muscle, Medically He is not only wrong, but also encouraging other's to follow that same path.
This is one reason why it's important to remain humble. if he continues on that path, he will lose more and more until he is a weak old man.
Perhaps my boring video's aren't so bad after all?
Thanks
