A generous blood donor has reached a landmark milestone after donating 100 gallons of blood over 35 years.

Florida man Harold Mendenhall, 84, began giving blood in 1977 after his wife Frankie was diagnosed with breast cancer.

Since then he has given 100 gallons, or 66 pints, claiming it has helped him cope with the loss of his partner who died seven years later.

‘For some reason, I’m still here and I’m grateful,’ he told the Palm Beach Post. ‘That’s one of the reasons I keep donating.


‘Giving blood can only be done by a human being, so that’s been my payback for my career and my good health and all the blessings I’ve had



‘It’s like getting a check-up every two weeks.’

Regular blood donors at the food bank he visits in Florida are rewarded with coupons for meals at a local restaurant.
