Everything we do affects our health but not necessarily for the better.
Doing physical exercises won't necessarily improve our health, but may be necessary to do sports.
The Chinese approach to health is doing gentle movements in a relaxed way
which doesn't look like you are doing anything, but over time is the basis of all health.
And can be done by anyone at their own level.
In the West, they use weights and pushing themself to do more. (pumping iron)
In the East, they do gentle movements with relaxed effort and postures. (Qi Gong)
Qi Gong is the basis of a martial art.
In the West, they concentrate on the Hardware.
In the East, they concentrate on the Software.
Perhaps we need to do a bit of both!
