Hi All, driving back from some dive sites over here (Scotland) means driving =20 through some mountain passes -- winter can be fun!!! Anyway, I'm not talking major altitude changes, well within the ascent =20 after diving limits=2E Despite the heights not being great, the change in =20= =20 altitude can be very rapid, enough to feel it in your ears=2E So my question is, is the speed of altitude change important even if the =20 altitude itself is "safe"? If I can feel a rapid pressure change in my =20 ears, is it doing anything to my tissues? I've never seen the rate of change mentioned anywhere but I'd imagine it =20 must play some part=2E Cheers, S =2E Visit our web site at www=2Escott-wilson=2Ecom Privilege and Confidentiality Notice=2E This e-mail and any attachments to it are intended only for the party=20 to whom they are addressed=2E They may contain privileged and/or=20 confidential information=2E If you have received this transmission in=20 error, please notify the sender immediately and delete any digital=20 copies and destroy any paper copies=2E Thank you=2E Scott Wilson Scotland Ltd Registered in Scotland No=2E 48951,=20 Registered Office: 6 Park Circus, Glasgow, G3 6AX=2E UK=2E ________________________________________________________________________ This message has been checked for all known viruses, by Star Internet, delivered through the MessageLabs Virus Control Centre.
