I'm definitely into writing because typing makes my hand hurt like hell. Plus, I'm more accustomed to writing because I'm fond of making notes rather than printing them. Even now that I'm in college, I still write my notes, but I can't deny that typing is much more convenient.
And as for my childhood, I didn't grow up with technology either. I'm not really fond of playing with other kids as well...because I'm more into spending time alone with books. I'm definitely a bookworm ever since, and I guess that influenced my fondness for writing :)
