Back home in London now, after my birthday weekend in Norwich (pizza followed by bowling).
I had a lovely time seeing my family, including two young nephews and niece. We had pizza at my brother's house, during which I counted down the final remaining seconds of my 30s – at 11.59am, the precise time I was born.
My presents included a virtual reality headset, a book on artificial intelligence ("The Creativity Code", by Marcus du Sautoy), a really useful book on London walks/tours, a gift card from Amazon, a voucher for Floatworks, and a chocolate selection from Hotel Chocolat.
It felt strange to be turning 40, which is a major milestone for me. As some of you know, I became very worried about it over the preceding months and years. However, now that I've actually reached it, I oddly don't feel worried at all; in fact it feels cool to be this age – and I'm excited about what the next 10 years have in store, especially when I look back at the progress I achieved in my life since my 30th.
Besides, 40 isn't that old. And I have some excellent longevity genes in my family, so if I can reach 90, that's potentially another 50 years of exponential progress in medicine/biotech, during which I could conceivably reach LEV.
