I have often wondered about something like what this guy is doing. My thoughts had been more directed toward primate chow, but the drink method makes sense as well.
Not to me, it doesn't, for myriad reasons (which I won't list now because I'm off to pick Shog up). Happily, my husband is not actually interested in trying the stuff.
That said, "primate chow" sounds more palatable to me than "Soylent." The movie still freaks me out, and I'm a big girl now. *shudders*
