Is temperature tolerance really that expensive?

My reading of the GURPS rules is that this is not the case unless the human has a level of DR with Tough Skin; 1d-4 cut or whatever still counts as 1 damage before DR even on a roll of 1, and thus causes an unarmored human who is hit by it to lose 2 HP from injury. The only damage type with an exception to this rule is Crushing.

You can even be an ST 1 pixie with an SM-6 sword, rolling something like 1d-11 damage or whatever, unless your sword has an unfavorable armor multiplier you still cause 1 cut or 1 imp to an unarmored human when you strike him.
