Pierre Cardin

So I was just sitting here and the thought hit me, "I wonder how Pierre Cardin is doing."  Turns out he's 98 and still going strong.  

Every year I'd get my dad this cologne for Father's Day; see photo below.  It was actually paid for by my mom or step mom.  Now, 40 or so years later, I look it up and it's this cheap ass 31 dollar shit.  I've bought him gallons of this shit over the years.  He’d go through this whole thing in a year.  Aftershave lasts me almost almost 2 years.   What the fuck was he doing with this shit, that he needed yearly replacements?
