Check out Jeanne Clement. I remember her when I was only 12 when she died. She lived to be 122... oldest person ever. Lived alone until 110... Walked until 115... Smoked until 117... Took up fencing at 85... Still rode a bike at 100...
Facts: There are only about 75 verified people (125 maximum with unverifieds included) born in the 19th century are still alive today. They won't be around for very long and will die off before the next decade. And... there are only two vertified men (6 maximum) left from that century still alive today.
Remember, it seems that the maximum lifespan that human being can live is about 120-125. Living to be 110-115 did happen over and over throughout human history. Only modern advancements made it possible for much more to reach that age, but the maximum limit still remains.
There are a bit of a pattern in the family. Especially my mother's side. Her grandmother lived to be 96 and I remember her quite well (I was 19 when she died). Her mother (my great-great-grandmother) lived to be 84. Her father (ggg-grandfather) lived to be 80. His mother to be 85. So I'm sure my mother will be around well in her 80s at least. Mom's dad was just an exception... died at 74, mainly due to unhealthy habits (smoking and drinking). Her other grandmother lived to be 89 and her son is already 85 now. My grandmother is already 85 and still lives all by herself, drives a car, walks without a cane, and just retired a couple years ago. Hell, she still dances for hours at family celebrations... including jitterbug! She'll prolly go on living to be well in the 90s. No family pattern... seven siblings died in their 60s and early 70s and she only has a 77 year old sister left.
