I know I complain about lawyers, but Althouse and Powerline are two of my most-frequented sites. I don't like the popup ads at Powerline, and recently they have been advertising a neuroscientist who says they can boost my IQ. I occasionally get spam emails of a similar nature, and see ads here and there for Lumosity or whatever.
Listen, I'm not interested in raising, or even preserving my IQ. I'm interested in raising the IQ of everyone else. That would improve my life more. I would pay $4.99/month for that.
Update: Come to think of it, that applies to beauty as well. Me becoming more handsome seems like a waste, frankly. Everyone around me looking better seems like a good deal, though.
