You’ll have to pry my cup from my cold, dry hands

Does Coffee Really Dehydrate You? My Quest for the Truth (With a Little Help from Perplexity.ai)

Let me set the scene: It’s Monday morning, my laptop is already making that faint whirring noise that says, “I’m trying, boss, but I might just give up any second.” I’m on my third cup of coffee, which, let’s be honest, is the only thing standing between me and a nap on my keyboard. In a moment of noble procrastination, I stumble onto this YouTube video by Dr. Seth Capehart, Navy Special Ops, ER doc, and all-around high-energy guy. The video is called “Doctor Reveals the SECRET to Sustained Energy Used by Military SPEC OPS”, and it’s packed with tips for being a high-functioning human being-something I aspire to be, at least until about 2:30 pm, when my productivity falls off a cliff.
Dr. Capehart is talking about hydration, and he drops this line:
“Most of you are dehydrated. Yes, you. Mild dehydration screws up your mood, your memory, your focus, your energy levels… so grab a water bottle and sip it throughout the day. And know coffee doesn’t count. It’s a diuretic, it actually makes you pee more. Drink actual water.”
Cue record scratch.
Wait, what? Coffee doesn’t count? As in, all these years of clutching my mug like a security blanket, I’ve just been fooling myself into a slow, shriveled, dehydrated state? I mean, I get it-water is important, and I’m not about to run a marathon on espresso alone. But is my beloved coffee really leaving me high and dry?

Enter: Perplexity.ai, My Digital Lifeline

Now, here’s where I admit something: when it comes to health science, I’m about as qualified as a goldfish with a FitBit. So, I did what any self-respecting, slightly skeptical, and caffeine-dependent tech enthusiast would do-I asked Perplexity.ai, my trusty AI assistant, for the real scoop.
And folks, the answer was… surprisingly comforting.

The Truth About Coffee and Dehydration (According to Science, Not Just Internet Comments)

Short version:
No, your morning coffee is not secretly turning you into a human raisin.
Longer version (because you know I love a tangent):
  • Yes, caffeine is a diuretic. It makes you pee a bit more, especially if you’re not used to it. But unless you’re chugging coffee like a sleep-deprived squirrel (guilty), the effect is pretty mild.
  • Coffee is mostly water. Like, 95% water. So, every cup you drink is actually helping you hydrate, not sabotage you.
  • Regular coffee drinkers build up a tolerance. If you’re a daily drinker (raises hand), your body basically says, “Oh, caffeine again? Yawn,” and doesn’t flush out extra fluids like it might for a newbie.
  • Science backs this up. Multiple studies show that moderate coffee consumption hydrates you about as well as water. It’s only if you’re drinking five-plus cups a day and not getting any other fluids that you might run into trouble. (Also, if you’re drinking that much, maybe check your pulse and your life choices.)
So, while Dr. Capehart’s advice to drink water is solid (and, frankly, your kidneys will thank you), you don’t have to banish coffee from your hydration plan. Just don’t rely on it exclusively-unless you want to risk the jitters, the 3 pm crash, and possibly writing blog posts at 2 am about hydration myths.

Practical Tips for the Caffeinated Masses

  1. Drink water, too. Yes, I know, boring. But keep a bottle handy and take a sip every time you check your email (or, in my case, every time your computer freezes).
  2. Enjoy your coffee guilt-free. It counts toward your daily fluids! Just don’t let it be your only beverage.
  3. Don’t overdo it. Five cups a day is the upper limit for most folks. More than that, and you might start vibrating at frequencies only dogs can hear.
  4. Listen to your body. If you’re thirsty, drink. If you’re tired, maybe try sleep instead of a sixth espresso. (I know, radical.)

Final Thoughts (and a Friendly Challenge)

Look, I’m not about to give up my coffee. It’s the glue holding my mornings together. But I’m also not going to ignore the wisdom of drinking plain old water-even if it doesn’t come with a frothy latte art heart.
So, next time someone tells you “coffee doesn’t count,” you can smile, sip your mug, and know that science (and Perplexity.ai) have your back.
If you’ve got your own hydration hacks, coffee confessions, or just want to commiserate about the endless quest for energy, drop a comment below. We’re all in this together-wired, tired, and occasionally hydrated.
Stay caffeinated, stay curious, and don’t forget to drink some water (your future self will thank you).

TIL a Cool PowerPoint Designer Hack

I don’t consider myself creative or artistic. The artistic bias probably goes back to school, where the requirement of an art elective ruined my chances at a 4.0 grade average (and exemplified by my Featured Image attempts, which even AI can’t seem to help me with).

The creative bias is that I usually can’t do it on demand. I’ve also learned that if you get out of your own way, creativity happens fairly naturally. This is similar to how Douglas Adams describes how one learns to fly. Anyway, one way to get over a lack of creativity and artistic sense is to let AI tools do it for you, and one that I find really handy for my handicap is PowerPoint Designer. (For those who think Designer isn’t AI, marketing is clearly doing it’s job, and perhaps missing the point, and here is proof— as long as the link is valid).

Personally, I don’t mind boring slides. I actually like have really basic slides where the purpose of the slide is for people to remember what we’re talking about when their minds inevitably wander. But, sometimes I am creating slides for other people, or need to meet the expectations of people with different opinions on the matter, so I need to make them a bit less boring, and designer is a great way to do that. One frustration I have with designer is that it so often gives me this message: Microsoft PowerPoint Designer "Sorry" message.

Usually this can be fixed by simplifying the slide, i.e., remove the cool graphic you added and let it focus on the text. Or you can split the graphic and text into separate slides and then combine the results after the magic happens.

Oh, and one word of caution: Copy your original slide before letting Designer have its way with it, because sometimes the new formatting is no longer easy to copy and paste.

Back to the cool hack part. My second annoyance with Designer, after it apologizing for having no suggestion of how to improve my work that clearly needs improvement, is that it gives so few suggestions. This seems to have gotten worst, and I suspect it is because those data centers are saving cycles for the AI that the marketing folks are calling AI. Recently, it was only giving me four or five options, many of which were just minot variations on the themes, like this:

PowerPoint suggestions for a slide with plain bullets.
PowerPoint suggestions for a slide with plain bullets.

I wasn’t too thrilled with any of the options, but I picked one just to move on and make some progress. Maybe an AI image would spruce it up enough (in the end, it did). Being the paranoid person who has lost early versions that I wished I could go back to, I made a copy first. Usually, when I make a copy, I start working in the copy. But this time, for no particular reason, I went back to the original…where Designer was showing entirely new options based on it’s own modification:

PowerPoint Designer suggestions after accepting a suggestion.

It seemed I had accidently cracked the code to get more options, like in the good ole days before everyone was using these tools, too. Just to prove my theory, I tried repeating the process, and sure enough…

PowerPoint Designer Keeps on Designing
PowerPoint Designer Keeps on Designing

I didn’t really find  an end to variations, though I admit that the quality of options generally declined, with an occasional interesting one coming up here and there. Full disclosure: this may have just been the raw material I started with, but that is back to my bias against my own creativity.

So, that’s my big discovery for the day. Well, there were really more, but I have to get back to “real work”, until this writing stuff actually starts paying some bills. Forward this to your friends (or enemies) if you would like to contribute to this hobby.
