--Boundary_(ID_DBhYKjQ7DQavmbR+3SrPmw) Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7bit Hello Bill, Just to be clear here: are you now saying that we don't need breaks from O2 breathing? Or, are you trying to do some damage control? To help you with this post, those were two questions, as indicated by the question mark at the end of each sentence. We wouldn't want you to think that was a statement, you seem to get that sort of thing confused. Also, my colleague pointed out that WKPP does the 12/6 split on O2 decompression to further reduce the impact on lung tissue, is this a fact, or was my friend misinformed? That was another question Bill, I hope this doesn't overload you.
