A lot of blokes are - and in this respect I'm no different - "trains, planes, boats & car" nutters, so it all sounds good to me. I suspect a 1909 1 cylinder Sizaire might not cut the mustard, unfortunately.
As to giving up the dreaded nicotine addiction ... speaking from bitter experience, I can say that it's the first three months that are the worst.
Good luck Kaye - hang in there: you'll never regret having tossed it.
