“He has a whisky in his tea every morning and two shots of Grouse in a glass with lemonade at night and swears by it,” she told the UK-based Metro newspaper.

The great-grandfather also uses the whiskey as medication. “If we’ve got a cold or anything he straight away gives us a whisky, that’s his medicine and it’s not done him bad,” said Goodwin.

Could there be any merit to Reynold’s claim? According to a study reported by the BBC in 1998, researchers found that both whiskey and red wine could help prevent coronary heart disease. (However, the study, conducted by the Rowett Research Institute, was sponsored by the Scotch Whisky Research Institute.)

More recently, scientists have warned that drinking alcohol raises the risk of cancer. Last year, the American Society of Clinical Oncology released a statement saying that there is no safe level of alcohol consumption.

Whether its the whiskey or just really superb genes, Reynolds is living it up in his centenarian years.
