Hey Beachie,
Would you believe ....he does have one. Great little machine. We tested it on the way back from Perth, seems my slightly younger lungs worked a fraction better. But have to say this, it was not much in it. The old doc aint too bad for an old fella!
We did some tests at various density heights and 10,000' is definately the limit for warm weather and low pressure for long periods. Would hate to be an unfit smoker as well....

Somehow I think you are not joking.......
