Lovely athlete of 1948.
I am an adult uncle of 34 years of age, and I, as you advise, do not have to run on the ice to avoid falling. And you, judging by rhetoric, at least twice as much. Or you are working in the field. Why did I make this conclusion? Because only these categories of people forget about the existence of the elderly and just people with musculoskeletal problems. I will not further develop the thought - if you already understood, I understood. And if not yet, then even after a detailed chewing you will not understand, and still start to argue.
