Thanks for that Ms Annie - Another also highly experienced member from a different forum gave me an interesting theory in that she suspects that the weaker muscles are more affected by antibodies. Her theory is that ´Embryologically cells know by position which genes to switch off and on, and so not all muscles are exactly alike and we may be set up embryologically for problems with certain kinds of muscles´........Fascinating.......

Good luck carving your pumpkin! - and a long rest between each incision!!!!!
