Apart from making TV programmes could someone please enlighten me as to exactly what the point of these trips are? These "adventurer" types ran out of things to do years ago & now seem to be constantly "re-inventing the wheel". There may possibly be a charitable element, but does the amount raised actually significantly exceed the costs of the operation? Like walking to the poles etc. it all seems rather pointless in this day & age, and just looks like a "look at me" exercise for those involved.
