Here is a photo of Professor Carl Wood with his ex-wife Judy. Many of you may not know his name but he was one of the world pioneers of modern fertility treatment and, in particular, IVF. He was one of the great medical minds of our time.

Today Alzheimer's has ravaged his mind. He has moved back in with his ex-wife who cares for him and he lives a simple but happy life.

We, as a community, were fortunate to benefit from his mind when it was active, and I continue to marvel at how fragile and mysterious intellect is.

Apparently his Alzheimer's has stabilised and he is no longer deteriorating mentally. He has earned the right to a happy later life, it is to be hoped that he gets it.
