It's no surprise that professional gamers aren't quite as fit as elite athletes, but they do have something in common. According to a British academic, top-level players show similar psychological attributes as top athletes, such as the ability to manage anxiety, and have reaction times on par with fighter pilots. Dr. Micklewright said, 'When I first got asked to do [the study], my initial reaction was "don't be ridiculous, gaming is nothing like sport." But the more I thought about it, the more similarities [became clear], and I became more and more convinced that it was close in many ways to sport.' While sitting in front of a screen might not have the same physical demands as running a marathon, neither do playing snooker or darts. Still, while gamers show good reflexes, their health was worse than expected, with one 20-something professional player showing the same aerobic health as a 60-year-old smoker."
