I have a few comments regarding the section on impulse control, while technically what you cited isn't wrong, I find some of its implications a bit misleading. For instance, wouldn't the graph detailing weakening impulsivity exclusivity towards younger age cohorts be proof of a widening (more prevalent) trend? Also the studies cited that provide evidence for decreased drinking and smoking don't provide data like increases in cannabis and nicotine use in younger demographics which would contextualise their findings. As for casual sex, worsening social skills for younger generations could be a factor, as well as declining T levels that would have men appear younger and less sexually attractive towards women who would want to engage in such recreational activities, unless were talking about prostitution of course, although given how little data I could find on it, this is probably not the case lol.

On the meta-analysis on handedness, the lack of relationship between being left-handed and publication year is only for 1976 and forward. I assume MLH focuses on changes since the mid-1800s

MLH posits constant degradation since the time of industrialization. Small e.g. 10-year timeframes can be criticized as being insufficiently long term, but this should equally apply to a trend between 1810 and 1820 and another between 2010 and 2020.

Nutrition is very important for public health. I strongly endorse the Plant Chompers YouTube channel by Chris MacAskil (https://www.youtube.com/@PlantChompers/videos) for information on nutrition. You won't find any other channels out there that compile so much information, studies, and analysis into their videos, in the same way MacAskil runs his channel.
