I worked in an old age home on school holiday and many of the residents would tell me their age followed by "you know." I've never understood the "you know" bit but love it, so I use it whenever I give my age. "I'm 28, you know."
@fesshole My dad, who is 81 and a cancer survivor, told me recently that seeing many people he used to know die at an age much younger than him made him realise that there are many ways to die before reaching your 80s, and he's been very lucky in that respect. He still enjoys life and wears his age like a badge of honour.
