Heavy breathing on safety stop

I suppose it will start talking loads of drivel now, get mega aggressive, make a bunch of false accusations, break down and cry "poor me, poor me" then set up profiles in my name across the globe

Oh well, if I do get around to playing it I'll be bored within a few days anyway. I never was much for computer games

It's not looking good. You'll be wearing special knitware next week!

Any thoughts on this please.

No, after a dive some or all tissues will be supersaturated at 3m, thus doesn't matter how hard you breath, you won't be taking on more N2 (Perhaps the uber slow compartments are exceptions to this - depends on the dive most likely - but even then you're unlikely to be taking on any extra N2 by breathing).

As for doing it all, probably a waste of time, more likely to increase the likelihood of the bends (heavy breathing being similar to exertion), though bear in mind a safety stop is NOT a deco stop, so offgassing N2 is not an issue anyways. In any event, the rate of offgassing is controlled by the halftime of the compartment, not your breathing rate, thus whilst perhaps the minimally increased gradient across the tissues *may* offgas very slightly quicker, it's still likely to be a waste of time.

Went cave diving Mon and Tues and didn't once stick to the ceiling Although I admit the ceiling arrived sooner than expected due to the lack of viz and angle of descent
