My nanna had 4 kids, survived 2 husbands dying of cancer (first, my mum's dad, from lung cancer called bakers lung from working as a baker in early 30's, second from pancreatic cancer in mid 40's) and was slim and fit until the day she passed age 92. Never used a walker and only had a cane to help standing up from sitting long periods or getting up from the ground when gardening. She was lucky and many nurses were amazed at her fitness and age. Thankfully her end came quickly so she never had to suffer being bed ridden which was one of her nightmares, being stuck in bed and slowly wasting away like several friends had gone. 6 strokes in a matter of minutes put her in an instant coma and she passed 2 days later when mum got notice that she was 'gone' and followed her wishes to be let go. My grandma was similar, she had 5 kids but remained fit and almost completely independent until she passed from organ failure at 91. Essentially woke up not feeling well one morning while staying with us as we were doing some work on her house, went back to bed, nodded off and that was it. The nurse who visited cause grandma cut her ankle pretty bad on some wire while clearing her garden said how she wished she could still be so switched on and mobile at her age. Neither nanna or grandma ever suffered any memory or mental degradation and lived well. I doubt any of those fattie shehams will live to be great grandparents and get to hold and be known by said great grandchildren like my nanna and grandma did.
