I have been noting this for while now by continuous occurrence.

This example may help you to notice if your long time cool IT buddy got himself into trouble.

Ever wondered where that IT buddy of yours that you used to see online all the time went ? What happened to him ? Is he gone ?

What happened to that online buddy that was always there for an intelligent information keystroke with you ?

Well search no more.
There are 3 reasons why a guy who has a brain, suddenly looses it.

1: drugs
2: wrong people to hang out (bad company, gangs and so on)

and finally ... the third one: women.

And this set of the factors, says it all. Drugs, gangs, women.

If you have an online buddy or even an outings buddy that all of sudden is "gone", trust me ... its one of those 3 things for sure.

And when he comes back; you will notice that for a while he doesn't seem to know how things work anymore. You talk to him about something that he used to know with his eyes closed and he just went back no n00b state.
