A question about the HUD.

[skillfultree (DayZ) 2]

I know that:

Knife and Fork = hunger meter

Water bottle = thirst meter

Droplet = blood/health

But!

what does the "head" and "chemical bottle" do?

Head will indicate if you are a survivor or a bandit, the bottle from what i've read on what rocket wants to do, i assume its more a tempreature gauge, he made mention of wanting the enviroment to play more of a factor, like you guy getting sick or an infection and stuff like that
