Hi Natasha and Jill,

Thanks very much for the replies and info: Will check out.

Best wishes,


P.S. for Jill: Thank you - it certainly sounds like good evidence for some genetic co-factor... (and indeed I also am tall and thin, my father died of prostate cancer, my grandmother of diabetes). Curiouser and curiouser, as Carroll had it, but there may well be some light visible at the ends of some loooong and dark tunnels.
