I thought those numbers were thrown randomly then the OP cited reference of the study.
Please edit the OP along with the reference you mentioned inside the thread, because some people don't go to page 2 and just straight up reply and ask for the reference for sure.
As for the 1%, even if knowing the actual number of that in the world population, that's already a lot of people and I don't think I would count on that.
Where are they right now? Probably not here in the forum so we'll never know. Probably they're still busy looking into their charts always.
