"fishing" may seem an odd one until you realise that it will include all the people who buy a small dinghy & o/b & then go sea & estuary fishing without anchor, l/j, vhf, oars etc - but do take plenty of booze with them.

Stats wise, the figures above (10ish fatalities a year in BSAC) rings a bell, but they include things like heart attacks, which, it could be argued, might have happened anyway.

It could, perhaps more plausibly, be argued that while the heart attack might have happened anyway the likelyhood of it proving fatal would be greater if it happened while diving.
Yes... The training for an Emergency Ascent to the surface teaches you to breathe out saying Aaaaaaahhhhhhh! as you ascend.
The small amount of air in your lungs at 12 metres, (or whatever), expands as you ascend, so you shouldnt run out.
Following a long career in commercial diving in the Gulf and West Africa with the associated safety rules & regulations imposed by the HSE and company procedures etc, I would suggest that 'Sport Diving' is dangerious due to the lack of controls and lack of experience required before you can dive. More experienced sport divers will no doubt jump up and protest at this point, but once again I suggest that everything from equipment maintenance to lack of control in the dive site (unlike commercial operations no surface cover is required, no communications, no real back-up air supply, no control over surface craft operating the area of the dive etc) are contributing factors.
If you choose to take up diving I plead with you to get trained and dive to a depth that suits your experience and that of your buddy. I have seen too many deaths and had to recover too many dead divers....
The chap who trained me in the 80s was an ex navy diver and submariner. He claims to have done an emergency ascent from a submarine, from over 500 feet, and breathed out all the way to the surface. Actually, he said he screamed all the way to the surface!
I can't corroborate that, but he swore it was true.
I quite fancied taking up diving as a fun thing to do from the bop but I read that people over 50 (which I am well past) were in substantial danger of heart attacks or coronary thrombosis and should not dive - is this correct?

Absolute bunkum if I may day so. Refer to previous posts re elder divers.
To become qualified you will have to take a medical which should identify if you are at risk. Basically if you are reasonably fit you can dive. A scenic dive to, say, 15m in warmish water is no more streuous than riding a bike.
