As we age, we realize that we are winding down. Whether we are running slower or walking or moving less, we are feeling and seeing deterioration. Whether it is the cartoon "Pickles" or the sport of Pickleball, we are developing sagging skin and wrinkles where we used to be smooth. You can pickle foods to keep them from rotting and pickling does extend shelf life.
If you are so inclined, you could inquire about time and aging. At what age should we expect pickling, deterioration, slower performance speeds and maybe less awareness, sharpness and memory? As usual, the answer is "It depends". Maybe you are lucky. Maybe you are exceptional. You might have aged more rapidly than many, or more slowly. It does depend on luck, nutrition, desire, and even denial all enter into the final result. Not only that, but if you are a northerner who is sensitive to heat and humidity, the type that flakes out at 90° and 90% humidity or a southerner who cavils at -40° and windchills of 25, the weather or your spine or your digestion might just be having a bad day. The luck of the draw and specific conditions of a particular day can skew things quite a bit.
The humans have not ever lived as long as they are doing now in today's numbers and they are just getting a handle on longer lives. Yesterday, as I flipped through the American Association of Retired Persons (AARP) magazine, I saw that AARP has its own YouTube channel and that one of the videos they have put up is about younger people and their ideas of aging. Remember when you were in your 20's and thinking about doubling your age to the 40's?
In this video, you see "millennials", young people explaining the ideas of what age people are old. Then, they meet some older people. Finally, they answer again what age is old. Worth watching.
