What can I say about Gary? I can say that if we were a bit more like him, the world would have a lot less suffering.
Before I got to know his work, I was already suffering the effects of porn addiction but I had no idea porn was causing it. It's so normalized nowadays and nobody had researched, or summarized the research, into it before him. A lot of people already suspected that porn was a public health issue, but it's really hard to defend something based only on intuition.
I can say with 100% certainty that, if not for him, my life would be much worse today.
Rest in peace, hero.
