Watching Ray Mears' Wild Food (BBC Two, Sunday, 7pm) with a hangover is a strange thing to do. Firstly, your self inflicted suffering makes you empathise with the hunter gatherers of yesteryear. You feel the pain of living rough and the hunger and struggle of getting up and finding something to eat. Naturally, it's also a fine way of noticing how spoiled we've become as suffering from a hangover is nothing like eating bracken and woodlice.

Ray Mears has seemingly become something of a cult hero over the years with one website proclaiming that "Ray Mears doesn't need to use condoms - he just builds millions of tiny sperm traps out of deer sinew and bamboo" and "Ray Mears doesn't milk animals, they milk themselves and give it to him." When Bear Grylls was still in shorts, Ray was diving around the woodland and surviving with not much more than a pen knife and his wits. So why was I a bit bored watching him yesterday?

Ray Mears isn't interested in becoming some all action hero. Ray is genuinely nice bloke who wants to impart some wisdom. This may well be part of the problem (although it may have been my horrendous hangover). I've seen Bear Grylls charging around and eating half a dead deer he found in an avalanche. Yesterday, Ray was content to eat a root with an eccentric old man with no social skills.

Still, never mind all that. Ray went on a voyage of discovery into the lost foods of Britain's Stone Age (or the Mesolithic age if you know about these things). Ray foraged around for roots and shell fish (he was on the coast) and cooked up a mixture of things that were "very good eating" and plainly nutritious... but disgusting. Ray it seems, is not one for the gimmickry of his rivals.

Ray drew on his wealth of knowledge that he'd gained from hanging around with various tribes from around the world which helped him to speculate about the processes that may have been used, and to find connections with the food of our forefathers. This show had a lot of talking in it. Mears and his pal went on with themselves about the energy spent in comparison to the calories got from the food. Pretty boring stuff. However, the more rewarding bits of this show surrounded the actual cooking. Watching Ray cooking limpets and razorshells on a flat heated stone in a glade was quite a treat. A gentle treat, but a treat all the same.

In fact, the show managed to make me feel a little dirty. As Ray tucked into a roasted root, the 3 day old Chinese takeaway that I was tucking into left me aimlessly chewing and wondering just how I'd cope if all my luxuries were taken away. I was left hoping that I'd be able to persuade someone else to do all the hard work for me whilst I invented songs for my tribes entertainment. Either that or I'd get eaten. [Mof Gimmers]
