A friend was driving me round Madrid today and I told him I always used a GPS to get to the shop we were going to. He told me he never used a GPS if he could avoid it as he had always been good at finding his way around, had good spacial/directional awareness and wanted to keep using it.
This struck me as a very good idea. I told him I used a calculator to check my 8 year-old son’s maths homework (I’m talking multiplications like 2,340 x 8), because it was a pain to think about doing it any other way. He was shocked – he does the sums.
I told him I can only remember three phone numbers now – my mobile, the landline, and my wife’s mobile – all the rest are in the phone, so why bother memorising them? He told me he makes sure he can memorise at least all the numbers of his family.
Clearly, all this tech could make me stupid. How are our brains going to be when we are 70 if we don’t have to exercise them nearly as much as we used to? Memory? Calculation? OK, we don’t need to memorise phone numbers any more and never will, but memory is still useful and it wouldn’t hurt to exercise it!
The most challenging thing my brain is doing these days is learning to sight-read music. I was thinking of ditching it as you can get away without it perfectly well on the guitar (at my level anyway), but I think this is one more reason it’ll be worth continuing – to keep my brain challenged! To keep it making new, fresh connections with new, tricky material.
And whenever I can avoid it, the GPS is staying in the glove compartment, I’d rather have fun getting un-lost every now and again using the compass in my nose!
