Once upon a time I could instantly remember where I put down a tool and return to it.
Once upon a time I could also remember a couple of hundred 9-digit part numbers, people's phone numbers or email addresses, license plate numbers for several days, books I had read years ago - Important stuff like that.
Not any more.
Now, if I don't force myself to put tools in a carry tray they seem to walk, I can't even remember my daughter's phone number (fortunately, my phone does and shows me her name) and I have no clue what the license plate on my speedster says.
None of this stuff bothers me. It's been a pretty crazy 70 years, and I'm looking forward to the next 30 or 40. Always looking forward, seldom looking back.
