I agree, we may be doing things to our brains that are irreversible but I also believe that it's something that we can control and manage.

I used to be an obsessive everquest player but am not anymore because I realized how unhealthy it is. Albeit, that's one small anecdote.

I think the real takeaway here, and I can't say if this article addressed it (because I refuse to read this) is that we as conscious beings have to take time to be self-aware and regulate our activities in a healthy way.

IE Eat your fruits and veggies, exercise, don't smoke, wear seatbelts, don't watch too much TV, spend a limited amount of time on computers, get outside, meditate, play music or draw, explore, expand and be creative and don't read too many alarmist articles.
