Buster Martin, a smoking, drinking, 101-year-old English man, is preparing to run the London Marathon on April 13.
Buster has 17 children and still works part time as a plumber. He recently completed a half marathon in 5 hours, 13 minutes. His first words upon crossing the finish line were, "Where's my beer?"
If Buster completes this race he will become the oldest person to ever finish the London Marathon.
