Basically, run outside and aggro the nearest zombie, then making sure he bites, or kills me.
Saves me a lot of trouble, seeing that I'll die anyway >_>.
You're lame.
Grab a katana or other weapon nearby and take as many of them with you as you can.
Just getting yourself killed or infected is so selfish. Just one more zombie for other survivors to fight, or just a mob of well fed zombies to fight...
