Let me be very blunt, if you cannot get up out of a chair or off the toilet by yourself, you are no longer physically independent. Talk to anyone who works in health care, especially with the elderly and you will see what I mean.
The best way to avoid that as you get older is to squat on a regular basis.
In many cultures, squatting is a normal every day thing. If they are not standing up doing something, they are probably squatting doing some kind of work, eating a meal, or just talking with friends.
How many people in Western cultures could do that? Not too many I am sure.
In these countries there are way too many conveniences and it makes the people weak and lazy.
So, it is squats to the rescue!
Any person who does Powerlifting, Olympic Weightlifting, Strongman, CrossFit, or Underground Strength Training knows the value of the squat.
Any reasonably person healthy person can squat.
There are many variations of the squat, so regardless of age you can do some type of the squat.
Some people will pay attention to this and take action, and others will just blow it off.
You can squat and keep your physical independence or you can skip it and just set yourself up for life in a nursing home.
The choice is yours alone, so choose wisely!
