So I thought about it and also talked to Daniel who pretty much knows everything that’s important to know, about the whole ‘Where does my food go exactly’ question I asked in my last post. Independently I had decided that mass to energy conversions don’t happen in your body, and that’s not why the volume of food-stuff decreases as it moves through you, but that food mass, like glucose or other sugars, is converted into other substances that you release, via cellular respiration, without you really realizing that you’re releasing them. Look at this equation:
We take in sugar and oxygen and produce water and carbon dioxide. Carbon dioxide we breathe out and water we can sweat or pee or also breathe out. So la-tee-da, there you have it. Obviously this doesn't give the whole story, because we don't just eat glucose, we eat complex carbs and protein and fat, but I think it's the same sort of idea. Except when you burn proteins and fats you produce some other metabolites like urea and ketones. However just to be sure, I asked Daniel if mass to energy conversions do actually happen in your body and he said “YES!” Apparently whenever you’re breaking down something chemically and releasing energy, the sum of the masses of the broken down parts will be less than the mass of the whole of the thing you started with. I’m pretty sure I learned that in some class at some point but in application, I guess it didn’t stick.
By the way, it seems like biology teachers, or at least all the ones that I know about, introduce the whole cellular respiration thing as, “this is how your body gets energy!” I think it’s a lot more interesting to introduce it this way, e.g. “Have ya’ll ever noticed that the volume of stuff that you eat is much larger than the volume of stuff you poop out? Why is that?” That seems like a much more likely thing to wonder about than, where your body’s energy comes from.
Science is the best tool I know of for making sense of things, especially biology since that’s what most of my questions are related to, and I think it’s important to convey that idea to students – that you can get a lot of your questions ANSWERED!!! if you just learn a little science!
I don’t know what body hair you can bleach and it will fix the issue.
Just because it’s blonde doesn’t mean it’s invisible!
Apparently most women use cream bleach to bleach their mustaches. I actually kindof wish I could grow one, but not a measely dirt smudge, I'd want a substantial nose neighbor. How cool would that be? :D If I had a mustache, I would want to find other people with mustaches, so we could rub our mustaches together.
When I poop, am I pooping the same volume of stuff that I put into my mouth? It sure doesn’t seem like it. I feel like I eat A LOT! But then every morning after the bunghole train has left the station, I examine my handiwork and I’m just not convinced! I mean, I know we break down food for energy, but what does that really even mean? (I realize I’m about to have a biology degree in a year, and I should be the one answering this question, but I’m confused) Is there really a conversion of mass to energy in my body??? I don’t think that’s what happens – I think the chemical bonds in your food are broken and that’s what gives energy, but the mass should still be there! Right?
I think many people get married to escape loneliness and maybe people truly feel like they’ve escaped it when they first get married, so they think they’ve succeeded. But really, it’s always going to be you inside your own head, with no one ever understanding exactly what you’re experiencing or thinking.
