The notion of 'alternative' as an asset class sits badly with me because for me, saying hedge-funds – as an example – are an asset class is akin to comparing mutual-funds to being an asset class. The sheer diversity within these groups makes it difficult to define them as a class in their own right, given the complete lack of commonalities across the board.

At the beginning I literally started a business out of passion. I loved fitness- it changed my life- it changed my schooling, education and taught me skills that changed my life for the better. I just wanted to be in fitness. When we started the business- whilst the first 6 months were difficult- it started to gain momentum and started to feel like a real opportunity. That's when I had to grab the business by the 'scruff of the neck' and drag it to where I thought it needed to be.

The brain is definitely not doing computation in the purest sense. We are not crunching numbers in binary ones and zeros in our heads. When people ask me how our system compares to an NVIDIA GPU in terms of FLOPS, I tell them they're asking the wrong question. A more important question is: what are your inputs, what output do you want, and how intelligently can the system get from one to the other?

Our body is a community of cells, in which each cell occupies a place appropriate for its tasks on behalf of the whole. Cancer cells, however, are rogues that trespass aggressively into other tissues. Metastasis is what makes cancer so lethal.

Today's civilisation is more fragile as a result of its complexity. We've created an astonishingly networked world in which we communicate and travel in ways which were unimaginable for most of human history... but at the same time, we have made ourselves more vulnerable to certain kinds of disaster, and even invented new forms of disaster that didn't' exist before.
