Another thank for sharing. My granny is 102 years old, and she's the one who reared us, since we had a working mother. She's physically quite feeble but refuses to use a wheelchair or any other thing. Only support she'll use will be a hand from one of us.
Mentally quite sharp still. Had she had a chance at proper education (girls were not meant to go to school in those days in India), she would have turned out a much more prominent figure.
My Granny can read and write and do basic math. That's it.
But she has one of the keenest minds i have ever encountered in terms of problem solving and cutting through the fluff and getting to the solution.
She is brilliant.
She raised me, and I am forever grateful.
