I said to my doc, “I don’t know which pains mean something is wrong and which ones only mean that I’m getting old.”
“That’s because you’ve never been 73 before.”
And that, just about says it all. In some ways the decades from 20 to 70, if you are in decent shape, have a certain similarity about them. You pretty much get up and go where you want to go, when you want to.
But in the later 60’s and from the on, aches come suddenly without warning and last longer. Getting up from a chair the wrong way can result in a twist or a sprain that simply doesn’t make any sense and has no business happening.
I mention this because it isn’t often mentioned: aging after 70 is a foreign country and requires learning a new language.
