To be honest, I always had this interest in martial arts media, such as the Kung Fu series with David Carradine in the 1970s.
Why raise the subject?
Traditional martial arts teaches control of mind and body. Mind and body are connected. Very often physical illness is caused primarily by stress. With martial arts you can develop concentration and meditation.
An example: A few months ago I started to get numbness in my right leg when sleeping. I suspected it could be circulation and, indeed, my pulse rate was a bit high. I finally decided to do pretty hard cardiovascular exercise, every other day for about 40 minutes. In time I became more energetic and the leg numbness has now disappeared.
Next I started stretching as I had the odd back pain. I just squeeze stretches in during any odd moment.
I am now looking at martial arts exercises to develop revitalisation of the body and hopefully easing of stress. I don't bother with hard styles but Thai Chi is pretty good for what I aspire to. Combined with exercise.
After just two weeks stretching, my back pain has eased and I feel ten years younger.
The dopamine chemicals you trigger by exercise help combat depression. More so if you can sleep well.
