Yup, at "our age", moving yourself is exhausting. Moving anyway is exhausting. I hope never to move again until it's feet first.
At some point, I guess "we" will be down to one person, and whoever survives might move to a smaller unit. I hate to think of that day.
I got three moving estimates, two of which were remarkably cheap, the third guy said "No way they can move for that price, they'll nickel and dime you to the same thing we're offering up front", which actually made sense. We took the (much) higher offer, and they were pretty liberal about how many boxes they'd move, we had more than the estimate by quite a bit.
And like most folks, we had to sell off or give away a lot of stuff we really didn't need or couldn't find room for here.
