Gaming. I’m in my 30s and the 30s was the age bracket I’ve heard where few can carry on gaming through, because it has a tendency to die here. I piss away so much time doing other things that gaming just takes a backseat. I’m not even married or have kids.
The people who say the brain stops developing are wrong and I used to be one of them. The study that belief is based on didn’t look at anyone older than that, so the real conclusion is that the brain is still developing at 25 and data has not been gathered on older people.
As far as I can tell people are still capable of learning into old age, so the brain is likely still capable of development.
