antrad88: I'm always surprised when someone on a gaming forum says they are 40+, but when you think about it those were the teenagers/young adults playing all the classics from late 80s/early 90s that grew up now.
In next 20 years we will reach a point when even the oldest generation of people had grown up with games, and gaming will be more accepted and people will stop saying it's just for kids.
Some older people also find gaming as a new hobby. I have one relative who started PC gaming (somewhat) when he was like 50 years old, and one or our former presidents, Mauno Koivisto, was revealed at some point to be a keen player of 8-bit Nintendo games when he was like 70 or more.
