No "wall" for men? Theoretically, a man's sexual market value...talk about "making merchandise..." can extend into his 50s. Of course, the mgtows are victory dancing. But, have they considered

their kids reaching their mid 20s.  Mr. Mgtow will be around 70ish, by the time junior gets his stem degree.  But that's only the beginning.  When a young person begins his (or her) adult life, he (or she) may need some help in getting established.  The starter home, for instance, will probably need work; junior will probably need his father's guidance - after all, the young man (or woman) knows computers and accounting.  But how to fix the ... whatever?  Dad had a similar problem a few years back, and while he was able to do some of the work himself, he also had another option:  money in the bank.  Dad called the contractor, he knew which contractor does the better job.

Not so, with junior.  Junior, with alot on his plate - and only having lived for 20-some years - doesn't yet know alot of things.  And junior doesn't have spare money waiting in the bank.  But how-to-fix-whatevers, is hardly even half of it.

Junior is in his mid-20s.  Dad is 70ish.  While the two men get together, to just spend time, while they can.  It's not like Dad is getting any younger.  But it is highly likely, that Dad will not likely be spending much, if any, time actually doing things with his future grandsons.  By the time, the first grandson is born, Pop will be leaning towards his 80s.  Grandfathers are important in a grandchild's life.  

In short, men do have a "wall."  Though it comes 1/2 century later than that of a woman's, it's still a wall.  And that wall, affects the grandkids, who are likely to not get to be around, and do things with their grandfather.
