I am the king of typos. I nearly always have to modify my posts. Lol

Hurry up Chotu! Why are you modifying your post? (Were you wrong the first time?)

HI Chotu. I've been AWOL and have just come back. How are things progressing these days with your health? I have a sight problem at this stage and I'm trying to get it fixed but with the pandemic it is pretty hard. It is a battle to read a rule or vernier. It would be great to hear how you are. Cheers Clive
