Are the older people also addictive to video games?

Well not really I guess, the ratio of older people playing games to young people is very low.

The older people are quite busy and don't have such time to commit into video games which are mainly played by much younger people.

The more attention you give to a thing the more you become addicted to it and like I said earlier young people give more attention to games than older people who have many responsibilities to take care of.

Though there can be exemptions but they are scarce honestly.
