Why is it always the most important emails that get eaten? I've been waiting for some coworkers to get a list prepared for me for a couple weeks, and they just asked me if I'd received it because they'd sent it a while ago and I never responded or did anything with it. I will never not be convinced that computers are malicious.

In other news, I've been experimenting with tracking my food and counting the calories in it, mostly just out of curiosity since I haven't really done it with any degree of accuracy before. But I am just incredibly bemused at how inaccurate it has to be unless you eat nothing but prepackaged food or weigh every single ingredient and then weigh your leftovers and subtract. Even then, you're still dealing with pre-existing water weight and the fundamental fact that no food can ever be fully standardized nutritionally. I mean, like. Most the time in the morning, I eat some fruit, some cheese, and some hard-boiled eggs. I'm weird about eggs because I eat maybe a quarter of the yolk, because I like a bit of yolk to flavor the whites but I don't like it as a dominant flavor.

Now, how the hell would you calculate this? I mean, theoretically yes, I could cut the egg apart, pull the egg white away from the yolk, weigh each, eat my eggs the way I like them, and weigh the remaining yolk and figure out the calorie content from that. But a) I'm not quite that neurotic about it, thank you, b) really if we're talking nutritionally varied foods, I kind of assume that yolk has to be one of the most varied just because I can't imagine egg laying hens don't adjust the amount of nutrition they give their eggs a lot based off their current health, because a sick hen who's off her feed and barely laying eggs just can't afford to give up as many calories as a healthy hen.

Or bacon. I've gotten some bacon that was mostly fat. I've gotten some that was mostly meat. Is there any sane way of calculating that besides some generic "bacon" ideal that's probably horribly inaccurate for the individual piece?

And then there's apples and really fruit in general which I have to think is just incredibly off. I've been alternating between baby Jazz apples and rather large Pink Lady apples and just entering the same amount because they're apples and I'm not weighing them individually to see how big a difference the differing size makes. How much of a difference is there between a Jazz and a Pink Lady nutritionally? How much is there between a Pink Lady that came from a healthy tree that was well-watered versus a Pink Lady that's from a tree that just isn't quite rightly positioned to the irrigation system and underwatered and also had an animal eat a hole through its trunk? Are you supposed to like, weigh the core after you're done? What if you eat the core? Some people do. Is that incorporated into any calculation of an apple's nutritional value?

Even prepackaged food isn't entirely a solution. I've known for a while that the FDA really doesn't have the power to enforce much on the food end of things, so I was really vastly unsurprised when I heard that someone did some unofficial studies that said nutritional labels are incredibly inaccurate. I'd google it, but I'm at work so I don't want to further distract myself.

tl;dr inaccuracy bugs me.
