This cannot be emphasised enough.
There is no safe way. The ability to back off is lost before they realise they need to back off.
Understand???
The people that die this way didn't 'push it to far', they just tried it and found out too late that what I just said is true.
Also, their life insurance policy might not be all paid up when they just start to remember, " damn, that last premium was due and I forgot all about it." You just can't get away with some things in life(and death) no matter how well you think you have everything covered. Almost isn't good enough once you start to hang.
