I applaud your maths! Pre-decimal makes me scream and run away. I suppose it is more attractive sounding that mere pounds and pence, but it makes my brain numb just thinking about it.

I'm very impressed with you XD

What you said about the middle classes is interesting. Watson would be considered middle class mostly because of his profession. This is when you get into the argument about blue collar and white collar jobs, which have less to do with how much you earn and more to do with how much education you've received to get that job.

I'm gonna stop now before I start to display my full socialist colours ;)
