I like Old Spice too. My dad also wore it -- judiciously -- and it has good associations for me.
And yes -- body chemistry affects how scents work (or not) on different people. There are very few perfumes that I can wear. Some of the most expensive ones smell like Evening in Paris on me.
Yuk!! And by way of comparison, Exclamation! (which is a very reasonably-priced fragrance) smells divine!! Go figure............
