The new phrase today is "maturity spikes." I just Googled it and found I'm the originator! Certain investment instruments in the financial sector have used the term, but here the definition is as follows:
Maturity Spike - An approximate age when an individual is expected to change his or her actions which are viewed by society to be more mature. The "overnight" duration is actually a steady climb in maturity over the period of approximately 1-2 years.
I've experienced different times of female maturity spikes over the years. First of all, many pubescent girls (ages 11-12 or so) are self-conscious and refuse talk to anyone except their parents and friends. This is not my observation, rather, a known fact found in many studies and books by authors with many more credentials than me. These findings hold in many countries.
The Teen and College Years
When they reach approximately age 14 Japanese girls will have no more maturity spikes for the next 8-10 years. They will simply mature at a steady pace.
When I first went to Japan I noted how teenage Japanese girls were much more mature than American girls. So while Japanese girls are slowly and steadily maturing over the 14-24 age range, I was under the impression that all American girls hit a maturity spike sometime during the college years.
However, since coming back to Japan I realized that is not necessarily the case for all girls, just for the girls I met during my college years. Since I'm no longer a college student, I've been exposed to a different kind of girl. This is baffling because about half of the college age girls I've dated are actually in college. Now could it be that the girls who are more studious are in school in the daytime and stay in on weekends, thus I'm not meeting them? And that the less studious ones just go to class and go home, thus I never met them was I was in college? Or that only the "party girls" are the ones willing to date a guy 10 years older than them?
Or could times have changed? I've noticed that American girls swear a lot more than they used to 10 years ago. Plus nearly ever girl I meet, college age or not, is taking some type of drugs for stress or depression. Could this be attributed to the type of girls I'm meeting? Here's a fact:
There are MANY more drug commercials on TV than there were 10 years ago.Here's another:
People, especially girls, are eating a lot more unhealthily.Could this contributed to bitchy attitudes and mental stress? One more:
Americans on average weigh more than they did 10 years ago, 10 years ago they weighed more than they did 20 years ago, and so on.Could it be that with all these negative factors girls are just getting dumber overall and when I was in college I missed the 20% or so who were dumb and these days 80% or dumb so I can't miss them anymore?
So it's either that I'm not meeting the same type of girls as I was 10 years ago; or that girls are dumber, fatter, bitchier, and sluttier.
Conclusion
Japanese girls aged 14-24 are maturing steadily and are much more mature than their American "party girls counterparts. Some are studious and some slowly discover alcohol and boys. This choice really doesn't affect their maturity.
Studious American girls reach a maturity spike sometime around age 19 and blow past their Japanese counterparts in terms of maturity.
However, many college age American party girls reach what we might call an anti-maturity spike when they discover alcohol and guys. They bring the dating drama, jump from guy to guy every week, get tons of tattoos, and get drunk and stupid every weekend.
The Ultimate Maturity Spike: Ages 23-26
Now we can take the party girls, the studious "good girls," the Japanese, and the Americans and group them together.
The cute, sexy, and slutty girls from either country will stop being drunk sluts sometime between the ages of 23-26. They might find a job upon finishing college. They will most likely want their next relationship to be a long one.
A huge difference, though, is that Japanese girls definitely stop dressing the same as they used to when they were younger. This is huge for many guys because in Japan I would never be interested in a woman (notice I didn't say "girl") over 25 simply because they no longer dress sexy but dress like an old lady. American girls in their late 20s who have stayed in shape, however, are virtually indistinguishable from girls in their early 20s. In Japan the visible difference is night and day.
In America, however, I wouldn't be interested in a girl who's under 25. Remember how there seems to be a dwindling number of respectable college age girls? Well, the large majority who are basically intolerable in conversation during the college years hit this ultimate maturity spike and get a lot smarter. Japanese girls, on the other hand, may be 22 year old sluts but they're just as capable of having an interesting conversation as a 27 year old is. And, since most Americans seem to be party girls, it makes sense that a 22 year old Japanese is more interesting to talk to than a 22 year old American girl, who is likely intolerable.
Also, another biggie: both American and Japanese girls spike in terms of wanting a relationship as opposed to one-night stands. However, American girls suddenly become a lot smarter and and cooler to talk to. They definitely surpass the Japanese in overall intelligence; and whether you'd prefer to talk to an American or Japanese 29 year old is anyone's preference.
The Ultimate Conclusion
In conclusion, if it's sex with many women that you want the place to be is Japan. Not only are the college ones more mature, but they're just as slutty and not even close to Americans in terms of overweight percentage. But, if it's a long-term, meaningful relationship you want look for a pretty 28 year old American who managed to steer clear of the food and drug problems.
