Getting older is great until you want to do stuff that was easier 20 years ago

For the past several days, I have been cleaning with help (paid for) from neighbors and family with the whole point being to set up the kitchen.  Dust is gone; all those large cardboard remnants that had been protecting floors are gone; showers are wiped down, beds set up, most windows washed on the inside.  So after a half hour search for the brackets/pins for holding the kitchen shelves, I find the shelves themselves too heavy for me to lug but worst of all is that the pins require strength in your hands and fingers to push into their holes to seat properly just isn't there.  Twenty years ago, I could do them in a snap.  Sigh
