Well, I had to answer the survey honestly, and say that no, I wouldn't - let alone three of them.
Three cheers for those that are willing to go through this: I guess, if he only needs 60 people, there are probably 60 or more brave souls willing to go along with it.
But I won't be one of them, I'm afraid. An invasive procedure is still an invasive procedure. It doesn't really tip the balance for me that I'm in pain most of the time anyway, and could reason: "What's a little more?"
Anyway, I assume he wants genuine replies from all shades of the spectrum, and not just from people saying: "Yeah, yeah, sign me up!"
To know whether such trials are viable, he presumably needs to get an idea, not only of whether anyone would volunteer at all, but also in what kind of proportions. If only 1 in 100 MSers would agree to it, he probably has quite a limited selection pool, but if it were 1 in 3, he's onto something.
I felt one thing the video didn't really address was that half the people who agreed to it would get no conceivable benefit (though they wouldn't know that), because they'd be on the placebo.
Although it's laudable to do something simply "for the good of mankind", I think undergoing THREE lumbar punctures, when there's a 50% chance you're on a sugar pill, is stretching goodwill a bit far. I'm not suggesting monetary compensation should be on offer, but if people don't even have the "consolation" of early access to a promising new drug, but might be taking nothing at all, it's tougher to justify, isn't it?
