It's a great point.
Initially I agreed that ageing wrinkly men don't lose a lot of sex appeal, and some actually gain it, but this thought conjures up the rare few in our minds, Sean Connery, Dolph, Mads Mikkelsen, etc.
But these are rare cases, let's look at what I consider the 3 big heart throbs of my generation (since the 90's) and Tom Cruise, Brad Pitt, Johnny Depp, they are all holding on to how they looked in their 30's. The wrinkles are not helping.
For an average guy? Without a team of people and possibly millions of dollars of ideas being pumped into how they keep their sex appeal? Getting old is not easy. Wrinkles are not helping.
Still easier than youthful baldness though.
