Code effeciency project:  handle_environment (human/life())

Before:  We process a whole lot of bullshit for no real reason most of the time because temperatures are perfect.

Now:	 We check if our temperatures and environment are within normal bounds and get the hell out of the proc.

Also:    Mobs that are long dead or just dead mobs spawned at round start won't process Life(), those 3 clowns don't need Life(), those jerks.

Code Effeciency project:  Damn monkies Life()

pretty much the same effeciencies from human/life()

no need to updatehealth() over and over and over
no need to process environment if everything is normal
etc.

Code effeciency project:  handle_virus_something() (human and monkey /Life())

2 for loops is more expensive then what we're doing here.
Also we check to see if virus2 is populated before starting a for loop
