I know I am very weird but I enjoy the feeling of stinging nettles, and usually sting my hands when passing a clump of nettle on my daily walks. I have heard nettle stings are helpful if you have arthritis, although I am not sure it has made any difference to mine! When I was two I was playing in one of our fields, wearing only my knickers, and I fell head first into a large clump of nettles. My mother couldn't understand why I wasn't crying in pain as I had been stung all over!
