Septuagenarian, or in plain English, a 70-year-old person.
Most people, when they hit 70, are ready to ride off into the sunset. For Gary Mason, however, age appears to be just a number. He's still battling on the gridiron, while working a full-time job as a repo man.
When asked about the time he started to play football, Mason had a rather amusing answer.
"1959, B.C.!" replied Mason. It's perhaps obvious, but Mason began playing football almost six decades ago. Football appears to be a family affair. Mason's son, Matt, is also involved in football. Both played for the Sun Devil football program.
"He's been around since leather helmets and one-bar face masks," said Matt.
Nowadays, both Gary and Matt play in the semi-pro Phoenix Outlaws football team.
"On the first time it happened years ago, I teared up pretty good," said Gary, recounting the time he was on the line, and sees his son as he looked over. "It was an emotional experience."
Gary may not have the biggest impact on the game, he does have a major effect on his team and teammates, as he leads by example.
"Pretty much, he motivates everybody -- with age, he's still out here, and let everybody else know that, 'hey look, I'm out here at 70 years old, how come you're not?'" said Ricco Verner, a Defensive End for the Outlaws.
