Hi JD.
I was just thinking when I read your post, how tough the human body is, especially when you are disciplined, are into doing what you are very enthusiastic about, such as one of the various martial arts.
I guess a lot has to do with your mind set and determination.
Even though I am very intense about martial arts, I will always remember
working out in gyms and observing the people who go that extra pound or kata or technique.
Some really put the body to a test, they live the life and every moment means go to the limit.
Seeing someone strain to bench that extra 5 pounds, so they can then bench the extra 10 pounds or 20 next week and figuring the amount of food value in protein they must eat to get to that next level.
Grapplers are in the same catagory, takes a lot to understand their mind set and if you can't, well you will never know.
Mountain climbers are another group. Most of these I refer to are really intense and yet very calm when not doing what they love best. Some carry it to extremes, they as a general rule burn out quickly.
There are many sports and activities we can talk about, when you realize the work and effort that it takes to get to the level of the professionals, we must all realize that the extra effort they take and do, we as regulars will never know.
I guess I am just caught up in the Olympics. Regards, Gary
