Old age is not i the mind actually, it shows physically no matter how good and perfect you are to people. Its not the mind thing, its the physical appearance. There are children that when they see aged people in their 90's, they will run away and would not even allow the aged people to touch them.
So many people have the fear of getting old because it will surely limit us from our capabilities. Inorder to stay fit, water is very essential in our body. Excessive sugar intake causes problems in our system. So cutting the intake of too much sugar is good for the aged.
People in their 90's may nit be so strong ti perform some certain exercise, so walking is recommended for such aged people.
You have a good post here. Best luck
