So the legal drinking age should be at 21?

A good point.

Yeah, countries that have a legal drinking age of 21 have a population that is much higher in IQ than those countries with lower permissable drinking ages.

Those countries where alcohol is illegal, Saudia Arabia for instance, are wellsprings of intellectual achievement, putting into shade any country where alcohol is freely available.

Plus you can be conscripted to fight in a war but not be allowed to drink therefore being less impaired when in battle

With that logic, you must have started when you were very young.

The lack of logic is beyond a joke.

I’m being somewhat funny, but one doesn’t equal the other, raising the drinking age will make little difference I imagine if not make it worse as people will drink to flaunt authority.

“Here we report on magnetic resonance imaging of developmental changes in the brain occurring during late adolescence and early adulthood (3.5-7.5 years) in a rhesus macaque model of alcohol self-administration. Monkeys were imaged prior to alcohol exposure, and following ∼6 and ∼12 months of daily (22 hr/day) access to ethanol and water. The results revealed that the brain volume increases by 1 ml per 1.87 years throughout the late adolescence and early adulthood in controls. Heavy alcohol reduced the rate of brain growth by 0.25 ml/year per 1 g/kg of daily ethanol. Cortical volume increased throughout this period with no significant effect of alcohol drinking on the cortical growth rate. In subcortical regions, age-dependent increases in the volumes of globus pallidus, thalamus, brainstem and cerebellum were observed. Heavy drinking attenuated the growth rate of the thalamus.”

In our talk of “Small Humans” it was noted that small brain often did not correlate to low intelligence.

I have to note the abstract did not mention how many macaques were involved, probably not enough to draw valid conclusions.

Well that’s alright, the people who wish to lower their cognitive ability can get sloshed everyday, whilst those who want to protect theirs can drink in moderation.

They makes sense anyway

According to article intro, legal drinking age should be 24 years.

71 macaques. That is enough.

Alcohol ingestion was self administered by the macaques. They chose how much alcohol they wanted to drink. This tangles up cause and effect to some extent, it could be claimed tyat small brain makes you want to drink more.

Have a look at Figure 2 E. The scatter on that graph is enormous. It would be fair to conclude that there is no correlation between alcohol intake and brain growth.

Yep. figure 2, A, B and C, spot the difference.

Well, it’s settled then, piss pot macaques with open access to the bar may or may not have slower brain growth than those that don’t…

How did they test it accuracy at faeces flinging, we conclude they aren’t as accurate, is that good or bad

Not sure why they needed to look at macaques. Surely there are plenty of case studies among humans

Monkeys are more scientific. Monkeys, test tubes, rats, flashing control panels etc.
