I still peruse Facebook daily, usually. I think it opens a bit of a window into ... something. Of late I've been getting bombarded with stuff about how bad "seed oils" are for humans. I looked into it a bit and found it all ... dubious, my word for the day I guess.
I also get a lot of "neutracutical" ads for things like "bergamot" or whatever herb is going to make me feel 20 again, and the first sample is free, only pay $99.99 shipping. They clearly make health claims along with a legal note that the FDA hasn't confirmed any of this burfle. They also include some pretty obviously faked testimonials.
