Paul Elam and I are very close age-wise, and another thing we have in common is type 2 diabetes, almost certainly the consequence of being overweight for too long. He’s lost 70lb, unlike myself, and I salute him for the achievement. His latest video (12:29) is particularly recommended for overweight men who have yet to contract the disease, the leading cause of blindness and lower limb loss in the UK and other developed countries.

If everyone who read this gave us just £1, we could change the world. Click here to make a difference. Thanks.
