I think the view of gamers are 20 years behind reality and uses outdated stereotypes. Just look at the comment in another thread that assumes 50-year olds play bridge, like being old means you are stuck in a 90s cliche of what older people do.
Why wouldn't we continue playing games? There may be a period in life where work and/or kids takes more of your gaming time, but once you get older you have more personal time that can be spent on gaming.
The average US gamer is currently 35 years old and increasing. 46% of American gamers are female.
