Spare eye

Always useful to have a spare, I would have thought...

Arguably, we've already got one.

Imagine you are on your bike cycling down a country lane on a summer evening. That swarm of midges have left you temporarily without vision. Not to worry when spare eye is available!

My favourite book in the department is a set of carefully drawn and labelled diagrams of different topics in biology. The anatomical models come a close second.

Did anyone see the bit on TV about hyper-realism a day or two ago? Now that is clever!
