hi @steevc, thanks for your encouraging reply, there are a few in the pipeline. I sometimes find it difficult to find the time but when I do the keyboard gets worked overtime :-) …. you hit the nail on the head - the capitalist system that Big Pharma i.e. working for the shareholders ultimately is a double edge sword, … on the one hand it encourages ground breaking research but then will also try to extract the maximum return when marketed, .. not sure what the solution is. iv never tasked a £800 bourbon - seems like you have great friends !
