You should. (Sounds like the kind of response I'd expect from Tony Abbott)
Most times a hole in a sock is merely at the toe, sometimes the heel, and a result of an errant toenail.
Darning with stronger wool or cotton will in fact make the sock even stronger.
Most darning I do takes about only 4 or 5 questions on QI per sock.
All you need is wool/cotton a large darning needle and a darning mushroom.
No need to throw away a good sock through a misplaced pride in your lack of basic survival skills.
