A: You have no idea if Les has people around him helping film that. There have been multiple shots where there's NO WAY he could have filmed it. It doesn't say when he's officially alone and not..there's a reason for that.
B: Les does not always catch food, most of the time he ends up eating plants and bugs why? Because he knows his rescue team is coming. You can survive longer than 7 days without food, but not without water. Notice when he was in the Moab region of Utah, they put him there in the winter when there is ice and snow patches everywhere. Don't put him out there in the summer when Bear Grylls was there.. why? Because he wouldn't be able to survive that's why
C: Bear Grylls doesn't need to be rescued because he finds his way out,.. Les tried this one time to make it out of a location and look what happens... He needs a helicopter and search and rescue to look for him.
what a joke.. Bear Grylls never needed search and rescue to find him.. never. He's made it out of every situation he's been in and he's still filming shows
