I wouldn't be surprised if Dorsey is only 2 degrees removed from Joe Rogan, for example. And in between those 2 degrees there are A LOT of influencers.
My own journey started with leangains (IF) leading into slow carb/keto, Starting Strength, a tourist trip to Iceland, some rabbit hole about xenoestrogens, another one about pesticides (actually that one goes back to Ruth Winter), Joe Rogan, Rhonda Patrick, etc. Something about it lends itself to forming strong opinions, but I know my journey is not very unique and many of you reading can probably relate.
