Short answer: yes.

Longer, somewhat more meaningful explanation: It's incredibly unlikely that what fits into your throat in terms of ice would be wide enough not to melt away enough for later passage… But what if that ice cube is also very long(*)? And what if your throat's internal temperature had already been lowered (let's say you're eating a bunch of ice cubes, outside, in the artic, as your sole means of hydration. In that case, yes, it is certainly possible that you could choke to death from an ice cube… But given all the other mitigating factors at work, I'm not sure I'd credit the cube itself with slaying you.

(* We usually call just about any squared-off three dimensional ice form a "cube", even if all sides are not of equal length)

Is it possible to choke to death after swallowing an ice cube?

No.

Weight has too many unknown related variables to ascertain solely from checkin data. Guessing weight is usually dependent on identifying body type and height to a high degree of accuracy. That's how they do it at the county fair, anyway.

Apart from body type and height, metabolism and activity level would be required to track weight changes from checkin to checkin. Did I walk from my house to McDonalds, or drive? How would Foursquare ever know? Hrmmm… Perhaps, using something like the iPhone/Android location data caches, we could get a "transit speed" estimate, plus "route taken" data, then map that to the mode of travel – foot, bike, automobile, train, airplane, etc.

That still leaves out caloric intake/burn and activity level… Maybe I'm jumping rope on the ferry boat from Alameda to SF, or maybe I'm sitting on my ass having one of their fine cocktails and a bag of M&Ms. You could find out, with some combination of credit card purchase history, access to the onboard security cameras, or a device I wear to track motion/activity, like the FitBit.

But… What about metabolism? For that, unfortunately, we really do need a combination of the above data over time, plus weight data for at least some of the same period.

Which kinda breaks the whole thing – you need weight at point A and B, to even start to estimate weight at point C. And yes, if you did have a way to measure body type and height via those security cams, plus an accurate calorie count of foods consumed, that would possibly work. But then, you'd already have so much other data on hand, that the checkins themselves wouldn't add much insight into weight specifically.

I'm vastly oversimplifying things in a way that'll probably make me look like an idiot to an expert in personal data analytics… But, after doing a lot of research in this area (the company name is NaviDate, after all), I've come to the conclusion that checkin data is very valuable as a source of insight – just not about weight. Personality type, income level, or even gender prediction on the other hand… But that's another whole question. 😉

Would it be possible to build an app that makes a semi-accurate estimation of person's weight based on their Foursquare or Gowalla check-ins?

Most major world religions have successfully sold the "ultimate long term play" for at least 4000* years now.

Which products successfully encourage long term benefit over short term temptations?

Whatever you do, track it.

Write down or photograph everything you eat. Keep a workout journal, etc… This single step outweighs every other single line tactic, since it allows you to have a constant measure across all the things you try, and to better understand over the long term, which things are working for you. I'd also recommend tracking anything but weight… Body fat, muscle mass, water intake, anything. Weight is the least reliable, since you can gain weight due to muscle gain, which still makes you healthier and more attractive than simply losing weight while, say, retaining the same amount of body fat.
