I gotta say, I've always put her long life down to lack of sex.
She had five children, the last born in 1954, lost her husband in 1958 and raised us single handed.
Only began to party in 1980 when the last of us were out of her hair.
The threads heading is in reference to an invitation when she was eighty, to go bungee jumping.
Her comment was "I never trusted the lackie in my knickers when I was a girl.....and I'm sure not going to trust it now"
She only slowed her tripping around down after she turned ninety five.
