Two years ago I had a bet going with my younger son about who could lose 10 kg the fastest. So I bought a Wii Fit unit.

Now I admit I am nothing but a grunt in the army of the techno-challenged. When it comes to gizmos and gadgets, the phrase "all thumbs" does not suffice.

I'm all knuckles, all kneecaps, all elbows. And the soft tissue — now mostly between my ears — doesn't help much either.
