I spent time working in fatal car crash investigation (reading crash reports and doing engineering analysis, nothing as gory as you’re probably picturing), and car crashes often involved massive head trauma or would, at a minimum, require *hours* of lag time before the cryonics team could make it there. I’d say at a complete guess that only about 10% involved people dying in hospital later on (i.e. under circumstances that a cryo team could get to them in time to prepare the body).
My impression of the technology is that it’s too much in its infancy to be able to say with any sort of confidence that a body that had been left with minimal treatment for a good 8-10 hours would be in a good state for preservation. And my understanding is that after only a few minutes/hours the brain starts to really degrade.
This is a major reason I’m not considering yet. I also live in a country without a good cryo organisation, and the exchange rates make the fees for Alcor quite a lot when I am not convinced I’d get the value. I also think the 5% figure is way too high.
I mean admittedly, pascal’s wager comes into play a bit here, but I’m not convinced that my current jurisdiction is a good place to die and be cryopreserved, and I have no plans to move.
I think the answer to your question is “people don’t concentrate for 2 hours at a stretch”. That’s why the pomodoro technique is so useful!
I’m very focused in general, and I find 45 minutes to an hour is the longest I can sustain my attention on a task, especially if it’s boring. Contrary to the other poster I don’t think that I have ADHD (though I don’t doubt I’d be able to focus for 3 or 4 hours straight if I took dexies, since my husband *does* have ADHD and the medicine does that for him).
You should look online for resources about combating procrastination, getting motivated, etc, as it’s the same sort of problem everyone runs into.
Here’s my personal productivity tips:
Pomodoros: I use the complice.co less wrong study hall, which has 32⁄8 pomos. I like that balance as 32 minutes is coming on the maximum amount of time I can be “mostly reliably” focused. I won’t bother explaining pomodoros as they’re on about ten thousand different websites.
Beemindier: I’ve been using beeminder since its official launch and it’s got me to do everything from an 1800 day duolingo streak to reading a textbook to writing a 50,000 word novel to studying several hundred anki cards a day. If I don’t, I have to pay $5, and I’m so cheap I’m not ever going to give up the $5.
I reward / bribe myself. “Can’t start making breakfast until I’ve done one pomo”, “that pepsi you’re craving will only be yours if you’ve done a pomo of project status reports”, etc. Only ever small things that I get immediately after my equally small achievement.
Don’t be too hard on yourself. The biggest thing that gets me in my work day in terms of productivity is my “shame spiral”. I don’t get much done which means I feel shitty about myself and keep on not getting much done, “the day is wasted anyway”. I try to think what my best friend would say to me and internalise that rather than thinking what a failure I am. Also, if I have a real shame spiral sort of day, I try to change my to do list to just one or two stupidly easy things, or break tasks down to steps the include “open the program”, “click on the link”, “type in the name of what i’m searching for”. It’s stupid, but it’s so motivating to give yourself some wins.
