It is not melodramatic, it is a technical term being used properly. You are perhaps thinking about the psychiatric usage implying a significant mental disorder, but here it just means that the system (i.e. metabolism) has been disturbed in its function, e.g. that it is out of normal range.

Pendantically yes, and yes, it describes the problem, and used medically it's not melodramatic, but looking at the original comments text: > It accurately conveys how completely abnormal the changes are. that would make no sense in the medically accurate context.

It's not a minor dysfunction.

Why kill yourself before thirty?

I don't want to be old.

I think Logan's Run was intended as a cautionary tale, not a model for how society should be.

Edit: Less flippantly, with age comes some benefits. Yeah, while I had a lot of energy in my younger years and could eat whatever I damned well pleased, as much as I damned well pleased, my attitudes of that time period, which were very much born of my inexperience, had some long term costs I am still paying for. But the tradeoff is that with those lessons, I can make better judgements on what actions contribute or detract from longer-term goals, or even what longer-term goals might be worth having.

If you play your cards right, getting older can be a good thing. So rather than thinking of being old as some terrible thing to be avoided at all costs, look to see how it could be played to your advantage. Come 30, what things would be fulfilling to be doing or having? If your answer is "nothing", then I think I can justly accuse you of not even trying to look.

"Walking good, sitting bad." But seriously, I think this sort of adds to the pile of evidence that even small amounts of exercise on a regular basis has marked health impacts. I'm a Type 1 diabetic so I have the benefit of a sensor that continuously tells me my blood glucose, so I can see the difference between when I'm walking on a daily basis to and from the office, and when I'm working from home. Same breakfast, v…

This machinery is quite finely tuned to an existence that involves a lot of walking, running, jumping, lifting, etc. Deviations from the active lifestyle are obviously going to have negative impacts of various kinds.

What kind of sensor do you have ? I am not diabetic but I'd like to monitor my sugar level somehow.

I use the Medtronic Guardian Plus because it ties into my insulin pump which then regulates how much background insulin to give me. Dexcom, as mentioned in another comment, is a standalone sensor that doesn't tie directly into a pump. All sensors that I know of are invasive though, so they have to be replaced every 7-10 days, which requires a needle and other things to cover it. You could also just buy a glucometer (…

>>you'd need a prescription for the test strips

I've bought them on Amazon before, no prescription required. This is to monitor blood sugar right?

The underappreciated role of muscle in health

I live without a car. I have no desire to change that fact. My condition is incurable. Running errands on foot plays a critical role in staving off deterioration that, among other things, puts me at risk for a form of diabetes.

"Public health recommendations promoting physical activity should incorporate advice to avoid periods of sedentary behaviour." How do we interpret and apply information like this? Many people work in front a computer these days so it can't actually be applied to them (read us).

You need to walk/exercise moderately at least 30 minutes a day. Though, granted, studies show that exercise doesn't fully offset the negative impact from sitting for hours at a time.

When I had a corporate job, I got up every hour on the hour to go the bathroom. It was a huge building, so that got me more walking in than you might assume from the description.

Sounds like a great combination of devices. How does your HbA1c compare on your current regimen? Do you also self-monitor, and if you do, have you tested your post-exercise levels? I have a number of patients who would benefit greatly from this setup. Thank you for sharing.

Obvious studies crack me up. It is a shame that PE is continuously being removed from many K12 school curriculums. If you get people into the habit of exercising and being active when they're young it's much easier to maintain that habit into the future.

The only thing most kids learn in PE is that exercise is awful and sports are only for jocks.

But, as I original pointed out, it's mitigated by maintaining a non-extreme level of activity - throwing on ~10,000 steps is the difference here.

To be covered by health insurance, glucometer testing strips have to be prescribed.
