Well to be honest the figures I heard was 14 in a life time , which is slightly more realistic but I assumed I had got it wrong when that thread came about (and some one quoted a yearly average) so I changed it to 14 a year.
I know this seems a little weird posting here instead of in the thread about spiders but it would seem rude to carry on an argument there. Anyway you said they had a list of sources , however all of those said sources just came from a book saying that it was made up and had no evidence to suggest it was not possible (scientifically speaking). I do believe that it is 100% possible to ingest spiders while sleeping , sure maybe the statistics of how many are eaten a year are false because seriously who can know that sort of thing? But speaking from the spiders point of view it will see a warm cave like structure , a perfect habitat , without necessarily knowing that it will surly die should it choose to take residence in the mouth , that's just how I think such a thing could happen. I hope I was not too irritating by carrying this on. Good day sir.
