Thanks for clearing that up for me! The jist of the advert was that driving a Range Rover is comparable to engaging in other adrenaline-producing/heartpounding activities (e.g. BASE jumping, car racing, martial arts). We found it kind of funny, though, because with freediving...well, we don't want our hearts beating that fast! Anyway, I suppose in the minds of those not familiar with the sport, it is indeed a "risky" or "extreme" activity, no?
By the way, viz wasn't too shabby in the couple of seconds of footage of Herbert's dive.
