I've actually been studying the looks of pro gamers recently to figure out how important environment is in the skeletal development and masculinization of males.

Main thing I concluded is that environment isn't as important as I thought it was.

This guy has been playing shooters in front of a screen all day for the past 20 years, looks way more masculine than the average male.

I noticed that many males that play shooters look a lot more masculine than strategy game players.

This proves to me that genetics have a far stronger influence than environment does, as all these pro gamers had similar lifestyles growing up.

It makes sense that males that decide to play shooter games would inherently have higher androgen levels.

These games mimic combat situations in real life and are reaction based which is masculine.

Which also explains why they are more masculine and look better.
