I wish to apologise for not responding to the comments and images in a timely fashion - I've been knocked for six by a really nasty cold, and have been unable to move for a few days!!
Fortunately, I was unable to get a close enough macro image of the virus itself, which I thought might be appropriate for the 'life' theme!!
Viruses are technically alive aren't they?
One thing I have learnt however, whilst bedridden, is that human eyes can indeed discern many more shades of green than any other colour!!
Thank you @Cobra, the worst is behind me and I'm on the mend thankfully.
Had to blow some of my GAS money on kleenex and lemsip though....sleeves can only do so much!!
Eew, can't believe I just typed that....sorry, still a bit hazy-brained!!
