She broke her hip about 4-5 years ago. The next year, she fell and broke he shoulder. Always bounces back and laughs.
She turns 90 in four weeks. She still works three days a week (think a real life version Peggy Carter - this one joined that government agency way back, with the original initials, but would have known a similar person to Peggy Carter). She has a couple of book clubs, gardening clubs, a new boyfriend from the same 'company' as my father in law was in, and is active. She rocks.
On bad days, she ..maybe.. drives me a little crazy, but I would not trade my mother in law for anything.
