Using 7 year old aftershave (Old spice)

It's perfectly safe to use. What i do advise is keeping it in a cool dark place away from direct sunlight. Hope this helps.
 
I have a bottle of Aramis from 2010 (before it was re-formulated) and it hasn't stank my house out, so it must be okay. It smelt fine the last time that I opened the bottle, anyway.

Seriously, OP, I wouldn't worry about it. If it still smells okay, then it should be fine to use it. Some aftershaves and EDTs "go off" much quicker than others.
