For me having a specific scent of cologne is ageless. Scents conjure memories. Studies say that smell is intimately linked with emotional memories and conditioned learning. It has the ability to directly associate experience, persons, and period of time regardless whether it’s negative or positive. One can easily time travel to the past just by scents and colognes.

I personally associate smell with my younger years when it was less stressful and having less responsibilities.

Those are my two cents!

Here’s a couple of good read about colognes:
