Why thankyou :-)

The b++++ in my geek code was not, in fact, a typo. I have a library of about 
2,500 books, and read 3-4 most weeks.

I concede that many of these are sci-fi and fantasy, but my management and IT 
sections are fairly comprehensive as well.

I do try to double-check what I type here, particularly detail stuff - for 
example, the stuff last night about the use of leaf as currency came 
from "Money - where it came from, whence it went" by J. K. Galbraith, which I 
finished about a month ago.

As it happens, Feynmann is currently sitting beside my bed on the "active" 
pile :-)
