Re: Autumn colours - North

Yes, it comes out (the needle, not the eye)!

I have it done about every month. Apart from the medical benefit, there are two others.

1) Sometimes a few bubbles are introduced. These manifest themselves as black spheres 'swinging' around at the bottom of the field of vision, thus demonstrating that images on our retina are inverted. The brain 'post processes' them to make them the right way up.

2) The second benefit is that it's a great conversation stopper if mentioned in company!
