If you didn't understand my point about back-testing I'm not sure how much more clearly to put it but to say that you are very wrong in thinking this is a bubble. As was everyone else who has been saying it for the last roughly 30 years. It is unethical, as I said in the post you originally replied to, to pull the ladder up after you. That is very clearly what was being suggested. I maintain that we should each do as our conscience guides. In answer to the question about doctors, tons of them. I personally know several who go to school career days and job fairs and evangelize the medical profession. There are also many who volunteer with charities targeting underrepresented minority evangelism specifically. I have worked with many such charities in a limited capacity to help them make their technology work better. In my discussions with them, many doctors share my feeling that our positions are a great blessing and that being in this position gives us an obligation to help as many others as we can. Finally, I'll say that in my opinion letting yourself off the hook because "nobody else does it either" is a pretty thin reed. If you don't want to help, that's your choice. I hope if you need help someday, others are more generous.
