What did childhood smell like?

Writer recalls the smell of cigarette smoke and the parties his parents threw when he was a child. Describes how he recently changed deodorant and began using Old Spice, which was the kind his father used. Smelling the Classic Original Scent Old Spice for the first time, he was almost knocked over by the physical memory of his father. The writer must now decide whether to stay with this deodorant, which would cause his brain to overwrite its evocative power, or save it for special occasions.
