The boy must have started worrying about my brain's atrophy as much as I have. Last week, he asked whether, if he bought a Brain Gym game for his Nintendo DS console, I would play it. Normally, when given the opportunity to try out a new computer game, I would answer with something witheringly negative like "Only if the alternative is to handwash your Y-Fronts for eternity" (Wii tennis excepted).
But he particularly emphasised the Brain Gym's reputation for re-building wasted grey matter, and - because I'd quite like to have an intellect again - I said I would.
True, I did do poorly in one of the games because I didn't understand the question (third time lucky though). But I was hooked for that brief time between dinner and my bedtime, and I could almost feel myself getting smarter. Although part of that might have been wishful thinking.
