With age, everything concentrates in a person - all the parameters of the mind and heart. But there is also physiology, by the age of 80 it dominates all parameters. When you neither sit down nor stand up, then everything obeys this, and \'physics\' begins to dictate. When you get up, and the knee does not unbend, then you become stingy, and angry, and greedy. And at the same time. And if the knee is miraculously unbent, then everything is ready to give, nothing to regret.

For the first time I understood the meaning of the expression \'weak in the knees\' about twenty years ago - it turns out that this is when, firstly, they hurt, secondly, they do not bend well and, thirdly, they become weak. I turned to two familiar luminaries on the knees - both gave diametrically opposite recommendations, and decided to wear the knees in this form, because I can't afford new ones.
