I had a random thought as I was explaining to my wife why I needed another pipe, my collection is around 60 (give or take). How many pipes could get you through the rest of your life, if you could never buy another? Taking into consideration of breaking and rotation. It seems that if taken care of, a pipe will last a long time. I have seen some still going strong from the 20's, although my oldest is an estate from the 60's. But I personally have have one burn right through on the first smoke (there was a hidden flaw in the wood that was no way the makers fault). So I thought it would be intresting to see what others thought. For me, I think I could get by on 15.
