How a 93-year-old soccer referee credits wartime rations and discipline for his longevity

At 93, sprightly referee Frank Foster is still brandishing red and yellow cards and running the field three times a week for his local soccer association.

Having taken charge of around 5,500 matches over a 46-year officiating career, the great-grandfather credits his longevity and match-day stamina to a lifetime of healthy habits and a foundational diet, news agency SWNS reported.

Foster puts his remarkable fitness down to the strict wartime rations he was fed as a teenager, noting that it ensured he grew up eating "healthy food" rather than "sweets and cakes."

His sharp mind and authoritative presence on the field are just as strong as his physical endurance.

A military veteran who aced his referee exam in 1980 with a 98% score, Foster relies on old-school discipline to keep matches under control, SWNS reported.

He has no patience for intimidation or theatrical diving. "Those who go down like they have been shot, well, I would just book them," he said.

He is equally uncompromising when squads try to crowd him on the field.

"I wouldn't let them surround me at all," Foster told SWNS.

"I would say to the players, 'Stay where you are,' and 'If you move one more inch, I will give you a yellow card.' You need to stamp your authority and let them know who is in control."
