Sorry to hear you didn't make it thru this time mate. Although it does sound very much like something I remember seeing on tv back in the late '80s / early '90s. I think it was on C4 or C5 and was hosted by some personality from the world of tv. The contestants, all regular people from all walks of life and with no experience beyond maybe the odd camping trip as a kid, were being trained by some ex SAS fella. They were taken off to some island off the coast of Wales (I believe) and had to survive for "X" amount of time. I seem to recall they were allowed to take 1 simple item of gear with them, like a knife or something similar. I remember watching one episode (it was a 1/2 hour weekly thing) where a couple of the people were trying to set snares for rabbits. As the camera man filmed them setting these snares, a whole herd of deer ran along behind them. I distinctly remember that bit as my ex wife was griping about the poor bunnies possibly getting snared and I barked back at her that if they had a 1/2 ounce of sense, they would ensure that one of those deer met with a "terrible accident"
I did learn something from it though.
Most of the people ended up eating mushrooms. LOADS of them as they couldn't find anything else to eat and their snares weren't catching them any food (much to the delight of my ex). The mushrooms gave them a dose of the squits and I remember the ex SAS fella saying on a voice over that the people suffering with it should powderise and eat some charcoal from their fire, as this would "bind them up inside". He then pointed out that had they of been constipated, he would have recommended eating loads of mushrooms and / or the seaweed they had been taught that they could eat. Funny how even the best ideas can be ruined by tv personalities. Who knows, perhaps this was the start of such drivel as "I'm a celebrity..." What a pile of crud, lol. No wonder I stopped watched TV just over 8 years ago!
