At what age do you start looking for things that you realize you're wearing or holding in your hand?

I sometimes feel in my pocket for my phone but then realized I have it in my hand, scary lol

Close to 70 for me so i've now been doing it for 6 years, the latest was a pair of shorts i was looking for to wash, searched everywhere until i passed a mirror and saw i was wearing them, the other day i was dressed to go out, walked through my front door only to feel the cold through my feet and realised i wasn't wearing shoes. not long ago i saw an old lady very well dressed with her hat and handbag waiting for a bus, problem was she was wearing slippers, i'd love to know how far she got before she realised.

As if I could remember when I started.  ha
I do remember that yesterday I looked everywhere for my keys for about half an hour and found them in my hand.
This morning I looked for my dentures for an hour and found them in my mouth. 

Hasn't happened to me yet .. but I'm only 72.

Right now I'm looking for my computer mouse . . . oh, wait . . . here it is.  (age 78)

It's been awhile, I'm 78.  I've actually gone through the house looking for my cell phone while I'm talking to my son.  The other night I had food defrosting on the counter, when  I looked it was gone. I looked in the refrigerator, everywhere in the house including my bedroom. It took awhile before I realized my new 23lb. rescue dog had dragged it off the counter.  So aside from my age related mishaps I have a four legged friend adding to the nuttiness.

Remember to exercise every day. Getting the blood flowing improves your brain and memory.

It was 60 for me.
