I had someone tell me that making sharp bends in romex was bad too.
Thats bull****. Electricity follows the copper. Bends dont matter.
When I wire something I always like to make it look neat bu bending
the wires around corners and keeping the bends tight to the structure.

Quote from (2000) NEC, Section 334.24:

"Bends in Types NM, NMC, and NMS cable (Romex) shall be made so that
the cable will not be damaged. The radius of the curve of the inner
edge of any bend during or after installation shall not be less than
five times the diameter of the cable."
