I thought he was gonna be 74 - same difference. My older brother is one year younger.
My two younger brothers jokingly won't tell me their ages when I ask....I have to look it up.
I'm lucky I have good genes....my oldest had a mini stroke a while ago....hardly any other ailments.
Re good genes, both overweight, smoking German parents lived a long time - father 76, mother 88, but both died of Alzheimers...as did my aunt.
BTW, German=eat meat, sausages 20 times

a day, plus my father worked in a butcher shop.
Re ailments, depression, social anxiety in the family.
