Oh so true.

Yes, I seem to remember you posting about your bike a while ago Phil. I think you might have even been up the road on it?

Some while ago I sent my poo samples away for inspection by the bowel cancer department. Imagine my surprise when I got a letter last week saying they had found a positive result. :shock: Anyway, I had a colonoscopy this afternoon at Addenbrookes hospital and they found everything is normal. :D It's...

An interesting combination of filling material Oliver.

I look forward to your views on the result.

The two pairs from Glasses Direct came yesterday.(Tuesday).

I'm pleased with the service, such good value for money for basic glasses.

I am agnostic about all this, but I do find it funny that the firsts post about making one is asking what goes into it. Aluminum powder and iron oxide may work well...
