When I turned 50, several years ago, on my birthday and such everyone had 'old man' jokes and laughs. I can't use the toilet without getting my balls wet, was a common jibe. I just shook my head and thought forgive them because they know not what they do. You are going to be right here where I am before you know it, if you are lucky enough.
Many of the guys derisively laughing it up, were in their 40s. So to them 50 is a million years away. They don't know the time creep arc. They do not know that from age 1 to 30 takes a hundred years. From age 30 to 50 is a blink of an eye. My only response was, hey man, you are tailgating me and you don't even know you are right behind me. Once you are as they say 'over the hill' you pick up speed on the other side.
What bothers me about being old is the burden of wisdom, which makes suffering fools almost unbearable.
