A little more on cologne, but it may seem a bit strange at first. If you are able, take your mother with you when shopping for cologne.nobody on the planet has a stronger sense for how you smell and what smells good on you. Never trust what the current girlfriend wants you to wear because the odds are that she is trying to make you smell like a past lover! Odor is the strongest link to memory and the last thing you want to do is smell like someone from her past. Try mixing two different odors so that you smell uniquely you but not more than three because it will become too confused. I personally wear Afta mixed with lavender oil which sounds really absurd but it just goes to show you have to be willing to experiment until you find what works with you particular body chemistry. If you go the route of pheromones then find one mixed with oils rather than alcohol. Alcohol destroys the chemical properties of pheromones.
A quick tip for the older set. It is ok not to color your hair but if your eyebrows are going gray then give in and color them. Nothing will make you look ten years older than gray eyebrows. Use a formula meant for beards/facial hair to do the job.
