Scott MosleyAccording to my 9 and 7 year old children, you are not "old" until you reach 80 years of age so, thankfully, I'm still a long way from being "old" 
I've been collecting cards starting with 1972 Topps since I was 7 years old. I probably had about 10-20 copies of each card in the early series and tired out of getting duplicates by the mid to late summer so, naturally, I was still missing a lot of the high series cards in my set.
My father and I came into a stash of pre war cards around 1975 and have been collecting pre war on and off since then.
