I get thi'!
I've never looked after myself, but have never smoked or took drugs, like a pint but didn't start drinking until I was 28 so I'm still catching up lol! I used to eat burgers and kebabs all day and night hence the cholesterol but now I don't, don't go all salad but chicken and Fisk, rice etc.
I used to be a decent boxer, and sprinter when young, probs fastest 100yds (at it was then) in school, but it all turns rank when you approach 40. Kids sports day, Annan, Dumfriesshire, 1998, I was 37, parents race, I though 'I'll pìss this' - 10 paces in knees went wonky and I finished second last! I was gobsmacked!
And also my BIL married a very nice young lass, very pretty, 28 years old a lot younger than him but hey-ho, she got cervical cancer was dead in 2 months. And she was a picture of health, certainly looked after herself which neither have me or BIL have. Must be gene pool related.
