The book is wrong. "Full" Life Support costs 50 points:

No Need to Breathe		10
No Need to Eat/Excrete		3
No Need to Sleep		3
Safe Environments (All)		9
Does Not Age		5
Immunity to all diseases		10
Immunity to all poisons		10
Total		50

Basic Life Functions
(Breathing; Eating; Sleeping; Aging)

These are all used as is.

Safe Environments

I've changed the numbers around a bit. The total for all Safe Environments is still nine points (9 pts.), however.

3		Character is Safe in All Extreme Pressures
		2		Character is Safe in Low Pressure/Vacuum
		2		Character is Safe in High Pressure
3		Character is Safe in All Extreme Temperatures
		2		Character is Safe in Intense Heat
		2		Character is Safe in Intense Cold

Immunities

These are all used as is.
