You become a 'Grand Master of Memory' by memorising 1000 digits in an hour, 10 packs of cards in an hour, and a single pack of cards in two minutes. It's comparatively easy, and lots of people have done it.
What nobody has ever done, yet, is become a Double Grand Master (a title which I have just this moment made up), by successfully memorising 2000 digits, 20 packs of cards and a 1-minute pack. That should be my ambition, really. I'm constantly frustrated by my inability to get 2000 in hour numbers, and it really gets annoying after a few years. So perhaps I'll devote my every waking hour to achieving that. Or maybe I'll just spend all my time lying around doing nothing, as usual. We'll see.
Possibly I'll change the definition of "Double Grand Master" by making it 1000 digits in 30 minutes, and 10 packs in 30 minutes, because if I do that, I'm one already. I'll put the initials after my name.
(Having written that, I had to go and look up who else is a DGM. It's me, Gunther, Hannes and Cornelia. Simon, the Deutsche Gedächtnis Meister, only has a best of 985 in 30-minute numbers)
In other news, I need new trousers. The pair of trousers that I think of as 'my only decently wearable pair' are actually decidedly indecent in the rear, thanks to a big ripped hole where I caught them on something sharp protruding from my bike. I ought to get some more before I go to Sweden. I don't like buying clothes, I tend to just hope that people will buy them for me...
