Lol old is relative! I have aged, dealing with a disappearing husband, mind, 4 acres of land, 11 ponds. 10 yorkies.
The ponds , easy.
The land, depends on how OCD a person is, mowing easy, gardens grown to be weedy, bees, bugs, birds, easy. Bush hog down
House cleaning for pups yep, the rest when I get to it.
The yorkies, non stop love , entertainment, joy, fun, love. Did I say love?
Better than just sitting and watching time march by. Keep darn busy.
Nails, I take all to a groomer, well not the babies yet. My hands can't handle the fine movements needed for using scissors. Pay her a car payment, once a month.
Three are impossible to groom, can't even get scissors near them. The groomer, no issue.
