This day in 1954, Sir Roger Bannister set a world record for the mile, also becoming the first man to run the mile in under four minutes, covering the distance on a slow track with difficult crosswinds in 3 minutes 59.4 seconds.
What's most amazing about this feat, in an era when the record is over 16 seconds faster, is that Bannister wasn't a professional athlete. Far from it. Although he worked with pacemakers and a coach, he was a medical student, working in a hospital. He trained in his lunchbreak and at weekends - and even went into work the morning that he ran the record-breaking mile.
Without nutritionists, sports psychologists or intensive training, he ran faster than any man had ever run before - and then hung up his custom-made running shoes and built a career as a pioneering neurologist, an academic and President of the Sports Council of Great Britain.
Today we're drinking to Bannister's achievement with a Three Miler.
It's also the Heart-Lung Machine's birthday
On this day in 1953, Doctor John Heysham Gibbon removed the heart from an 18-year-old girl and connected her, instead, to a machine. She lived.
And so, in her footsteps, have followed hundreds of thousands more. Before Gibbon's invention, heart surgeons had to operate on a moving, beating, blood-filled heart, with all that that entailed - many heart conditions were simply fatal. Gibbons had spent almost twenty years designing his machine, which functioned as both heart and lungs, by taking deoxygenated blood from the body, filling it with oxygen, and then pumping it back in. But, after two children died in surgery later in the year, he abandoned his research, and left it to others: a smoker, Gibbon would himself die of a heart attack.
We are toasting Doctor Gibbon, and his great invention, with a Doctor Cocktail, based on Swedish punsch, a liqueur that's undergoing a long overdue revival.
