How old are you if you "grew up playing video games"?

The Today Show had Kerry Sanders showing off the pilot stations where they operate the subs trying to repair the blown BP oil well. Sanders says that apparently the 20-somethings are the best operators of the vehicles, and he leaps to the conclusion that it's because they grew up playing video games.
Maybe it's because they have better twitch reflexes than 40-somethings.
Maybe it's because they have better concentration than 40-somethings.
Maybe it's because they have better tolerance for parking themselves on an isolated ship than 40-somethings.
Maybe it's because they have better environmental consciousness than 40-somethings.

But to say it's because "they" grew up playing video games, and the 40-somethings didn't, is completely wrong. Videogames go back a long, long way, and today's 40-somethings were the original purchasers of the Atari 2600, Mattel Intellivision, and Colecovision. They grew up in video game arcades in the 1980s (you remember those, right?) and didn't have to be taught to use a mouse when Apple released them on the original Mac. They were the ones who bought the original NES, which was released when today's 20-somethings were 3-5 years old. They bought the original Xbox in 2001, and might've played the games with their teenage kids, who are not 20-something and operating subs trying to repair the oil leak.
