Very few people can actually hear a tech speak. This law does not apply to common conversation. A tech needs less food and sleep as the tech aura in the area he is in increases.
Users have a negative effect on the tech aura.
Under this law all the present techs should be able to survive on a 15 minute power nap and a granola bar for about 2 weeks. A tech can store anything anywhere. Pulling a rack mount server from one's pants is not difficult for the fully empowered tech. The strength a tech possesses is relative to the item he wishes to carry. An item with little to no technical aura, like a dumbbell, is nearly impossible for a tech to lug around, regardless of the mass thereof.
