I recall reading that it was upwards of 40 passage

I recall reading that it was upwards of 40 passages (could be wrong) with no sign of resistance. That's impressive.

I wasn't meaning to be contrarian about resistance developing. I think the proper scientific approach is to "never say never". It's going to be fascinating to see this play out the next 2-3 years.

Back to lurking mode.

Thanks for the several welcome messages.
