Increased thrill seeking activity includes sex. The evolutional advantage could simply be more chance of passing on genes; from that point on it doesn’t matter if you fail at life, get outcast from society and/or die young.
Today we're much much more about conformity, rigid structrures, time management, and so on, than 4000 years ago, or even 50 and 100 years ago.
And today we're much less about having extended families and communities that take care of their members and lend a hand.
At best we have some half-arsed provisions by an indifferent state, and we're left on our own. A slip and you're broke, or homeless, or depressed on your own.
Is this likely? My overgeneralizing gut feel would be that more people who would have traits which might be perceived as unusual and impede survivability 4000 years ago would be more likely to receive a chance to live a regular lifespan in most today‘s societies.
