I am recently thinking a lot about this decline too specially because I'm seeing it in my own family with rapid decline and it is very sad to see. They don't realize. They make the usual jokes about age and such but I'm sure they are not very aware of the extent of the problem. Even simple problems become huge. And it reminds me that while I still feel great I have only a small number of good years left and that is counting that I would not get any other illness.

Make the most of your youth. It goes fast later.
