Would probably be a good idea and you can get a heavy duty power chord for around $50-$70 and just put a thin towel (a washcloth) around where your neck would be and make sure it's around a sturdy beam or tree limb. Also, doing such in the woods during winter with nobody around would be preferable and if you aren't found animals can consume your body so that others won't have to find your body until it's a skeleton which would prevent more trauma.
