Thank you for your clarification re pulses.
Yes, I was 'Philoz' but was encouraged to put my locality, Melbourne Australia up, making my name semi-superfluous, so I took the opportunity to opt for something a little more MS cryptic. Hence 'Brainteaser'. Sorry to confuse.

Please don't change from 'Anecdote' which I like, very much. It is has the right amount of restrained positivity........ as distinct from the average MS medical practitioner who reflects unbridled negativity, (in my opinion).

Regards,
Phil.
