She's a good person, who has had a good life.
We should all be so lucky to have seen what she has in her life. Born into the WW1 as part of the first true generation after the devolopment of the industrial revolution, she lived through the roaring 20's, radio, prohibition, the great depression, TV, air travel, WW2, the nuclear age, the space age, the computer age, civil rights movement, the internet, genetics. I'm sure I missed more than a few important passings in there, but she lived during IMHO the most exciting period in human history.
It was not until shortly before she was born the average day to day activities of most people were no different than their parents, or their forefathers of hundreds or even a thousand years ago. Life was a daily struggle to provide the most basic of necessities. This lucky woman got to experience and contribute to something that might not happen for another 1,000 years, a period a of profound change and advancement of humanity.
So sorry about your grandmother. Sincerely hope she is able to recover and share a bit more of her amazing life with her loved ones.
