There was a time when Sunday afternoon TV was a family safe experience; apart from Songs of Praise that is.

Now, however, I am forced to get through my well-earned weekend slice of toast whilst watching someone called Bear Grylls eating all manner of creepy-crawlies.

As I write he has just caught a beetle, that seemed to be minding its own business, and popped it in his mouth without thought for what it might do for my digestion. He followed this less than appetising starter with a main course of moth maggot. He first removed its innards before consumption because otherwise, apparently, it would have been disgusting and contain something harmful. To say that he was trying to present it as an enjoyable experience he seemed to do a lot of spitting out.

I think the point of the show, apart from putting me off my mid afternoon snack, is to remind us of our long lost role as hunter-gatherers.

Well let me nail my colours to the mast and say that I am truly glad that we have moved from hunter-gatherers to shopper-baggers.

We might have become slaves to the sell-by date and the nutrition label but at least you know where you stand with a bag of salad leaf and a tin of tuna.

Whilst Bear forages in the undergrowth of Latin American countries I am happy to dodge the shopping trolleys of the Great British public in order to makes sure that my family doesn’t have to eat grubs and bugs; give me fruit and nut any day.

The only bit of foraging we do in the supermarket these days is when we chose loose fruit and veg rather the pre-packed product offered to us. Perhaps this is the retailer’s way of appealing to our basic need to feel as if we are fully involved in the gathering process.

This said, I have noticed a similarity between Bear Grylls and me on a Saturday trip to the shops; neither of us can get a plastic bag without an argument. His need for them is less than mine because he does tend to catch and eat his prey almost in one move.

When our kids where younger they seemed to have this immediacy as an in built mechanism when it came to the pick and mix sweet section. Whilst we parents were looking around the shelves for our required produce they would appear with chocolate stained faces.

My wife was always fearful that we might be challenged by the management about our children’s’ waywardness but I had a solution ready to offer the store in such circumstances.

They could weigh the child on the way into the shop and compare this with their weight at the exit and we would willingly pay for the difference.

I could, of course, just claim they were exercising their basic instinct to be true hunter-gatherers and if all else fails blame the influence of Bear Grylls.
