This is a follow up to the thread Unbelievable Video. How do we perceive risk.
Same kid, different situations. Rate them as to greatest risk to least risk.
1- Riding a bike on city streets with friends
2- Riding behind his father on the father's motorcycle
3- Playing organized football
4- Riding a dirt motorcycle or 4 wheeler in the woods
5- Diving with his father as in video
We don't know the variables, but here are some facts.
In 2006:
There were 72.34 deaths and 1,311 injuries per 100,000 registered motorcycles. Source NHTSA.gov. (USA)
There was 1 football fatality (3 in 2005, 4 in 2007). Source National Center for Catastrophic Sport Injury Research. (USA)
There were 773 pedalcyclist fatalities. (USA)
DAN's 2006
Report on Decompression Illness, Diving Fatalities and Project Dive Exploration states "the annual fatality rate for DAN Members between 1997 and 2004 varied between 11 and 18 deaths per 100,000 members per year." (DAN members, statistics might not reflect the SCUBA community as a whole)
Based on this information, my order, from most risky to least, is 24153. From the statistics I've seen it's clear operating a motor vehicle (or being on the road) is riskier than diving.
That's a simple risk assessment, but to add to that more people would die from motorcycle accidents, bicycle accidents, and organized football if they weren't wearing helmets, leathers, pads, etc. "NHTSA estimates that helmets saved 1,784 motorcyclists' lives in 2007."
Not having the proper equipment puts you at a greater risk of injury or death. It is clear to me that the kid in that video did not have what most of us consider basic scuba equipment, and is by logical reasoning at greater risk of sustaining injury or death.
There's something else to point out, DAN lists the triggering event for the fatalities (i.e. the first problem). It was insufficient gas 14% of the time. Now do you consider one tank sufficient gas for two people? I don't, but I guess the guys in the video do.
Just a note: I couldn't access DAN's actual report, but rather found it reported at
http://www.scuba-diving-smiles.com/scuba-diving-deaths.html; I cannot guarantee it was corrected cited. Logical reasoning still applies, however.
