10 kids in one year got run over buy parents backing up. solution???? legal mandate camera on all vehicles 2015 and later. So you can do that but you cant disable a phone from sending in a moving vehicle knowing that using it has caused thousands of deaths. I guess the kids aren't safe when the village is addicted to cell phones.
Paragraphs are your friend...
It's funny that in a thread about not knowing what you don't know people are so quick to make decisions based on what they don't really know.
I have gotta take the character assessment Of Tstorm, it's a judgment call. It really doesn't sound like this Gramp has a solid skill base...
A long time ago when I had to work for a living, my duties included safety officer so I do understand risk assessment and mitigation. And I respect your right to make your own risk decisions. My gripe is when someone who is not in a position of authority tries to decide to make those decisions for me. Their store, their rules. But . . . .
None of us knows what we don't know. One of the things you seem to not know, and you're far from alone, is that you don't have a clue about grandpa's competence or knowledge. The only thing anybody knows about his diving ability from reading this thread is that he has very little recent experience actually going diving. This will apparently come as a shock to a lot of people, but that doesn't tell us anything about his knowledge, his competence, or his judgment. We don't know if he made 100 dives or 5,000 before the last 10 years. Something else we don't know is what he meant when he said he wanted to take his grandkids diving in the family pool. He might have just been planning on letting them swim around on the surface while breathing from the reg, he might have been planning on letting them sit on the bottom of the shallow end, or he may have been planning on actually teaching them to dive.gotta say it depends totally on the diver ... I see ppl like this guy all the time, they don't know what they don't know
It's an absolute certainty that something could happen. I see no evidence that the chance that something would happen is significant.I think it is likely something could happen
