I've been using this service since shortly after I had an autoimmune attack that ate away a chunk of my nervous system about 8 years ago where I nearly died(technically, did kill me at one point for over a minute before they revived me). I went from being pretty much like you blokes, lost in the details of living without seriously thinking about dying...But i mean, who doesn't in their late 30s. It's easy to get tied up in your day to day concerns until those days start becoming distressingly short. Thankfully, I survived that, and the five years of rehabilitation it's taken to get me back to some shade approximating "normal", though i'm still very functionally and impaired and will never again be what I was...But such is life. Life is 10% what happens to you, 10% the available choices of your circumstances, and 80% how you CHOOSE to feel about it.
All that being said, it's important to remember, the only people who know how and where they're going to die are suicides and people on death's row. The rest of us don't. Having lost many dear freinds and family over the years, I can tell you all unequivocally you should consider what you'd want to say to your friends, your family, even your most cherished rivals....Because statistically, at least one in one in three of every one reading this will die unexpectedly(heart disease, car wreck, lingering crotch rot from a unsanitary toilet seat, et al). Another third of you will get a terminal diagnosis only a few months before you expire because you put off "having that thing looked at like you've been meaning to" until it was too late.

I want that to sink in to all of you. Two of three of you wont have time for carefully crafting what you want to say, or to whom...Because you'll either BE dead, or WILL be shortly. And what i'll bet most of you want to say isn't about where you buried the treasure chest of Al Capone, or that you're the secret love child of Ronald Regan and Janet Jackson...It's that you love them, that you treasure this and that shared memory with them, and that you wish for them to remember you a particular way, or perform a certain ritual in your memory and honor, should they choose.
Sure, this database wouldn't be hard to hack. What's in there is almost completely useless to anyone other than their loved ones. can you imagine how depressing it would be to read a hundred thousand dead people's communiques to snag the one juicy bit about some senator being the illegitimate son of Prince and Madonna? Yikes!
All that being said, I've spent quite some time thinking on this subject, and the answer I keep coming back to on the "Verifying you're dead" problem I think should be handled by examination of the customers data footprint in some sort of routine way. If any of you have ever done data analytics or doxying, you'll know that there are some distinct signs that start to appear when your subject focus has died or dropped deeply off the grid, even after a few days. It seems to me that such qualities could be mathematically modeled into a set of software scripts, and that tied to the trigger. With a failsafe of primary and secondary inquiry designated by the client. I have a few other ideas along these lines that prudence dictates I should keep to myself until it can be developed and patented properly.
