It’s totally true from a physics standpoint. A longer lever arm between the load and fulcrum requires more force to move the same weight, all else being equal. Edit: thinking on this more, I think a type 3 lever is more applicable to my chest flye example, but the same concept applies; as you lengthen the load arm relative to the effort arm, more input force is required to move a given load.

“Harder to exercise” is poorly defined, especially when you go on to discuss endurance, speed, and force, all of which are very different terms.

I totally get what you’re saying, but I specifically narrowed it down to force for a reason. My shorter friends kick my ass in lifting due to the mechanical advantage their shorter limbs have, but I smoke them in a distance run because my longer limbs allow me to traverse a greater distance in a single step. This is complicated though because larger lungs are a factor here too.

The smaller the foot, in this case, the harder the muscles have to work to create the same torque (or moment).

That’s backwards, a shorter lever arm requires less force. If you had a 10 foot long foot, you’d have to have insanely strong calf muscles to stand on your tip toes, because how far the load is from the fulcrum.

torque is the cross product of force and length

Correct. The force at the end of the lever is your body weight. A longer foot thus exerts more torque on your ankle and requires more calf muscle to move. Longer arms don’t make chest flyes easier, they make them harder.

That would be relevant to the calf muscles, but the lower surface area of the feet means higher pressure in terms of psi or pascals.

I vacillate between the two. Really depends on the words surrounding “data”.

How did you learn English?

Just use it all the time including turn only lanes. Deal with the clicking, it’s fine.

Limited access photos isn’t pretty new, it’s been around since iOS 14, we’re now on 18.4. Gotta be at least 3 years old at this point.

I know the DSM isn’t perfect but inattention, hyperactivity, and impulsivity are the main criteria, and those are all issues that I believe stem from poor concentration or focus.

My opinion still remains the same; I think many have these traits but few have it to a level which is appropriately classified as a disorder. Stimulants are performance enhancing drugs for your brain and they have side effects. People hear from a friend or post online that it helped someone and go get evaluated - by a for profit industry that stands to make money by getting more patients. Pretty easy to cut someone a script and bill that CPT code.

I’m not saying this disorder doesn’t exist, or that some people have no option but medication. I do think it’s over diagnosed by an industry relying on patient satisfaction scores.

This is my unpopular opinion. I don’t believe taking a medication for life as the first line treatment is appropriate, especially when they’re directly affecting reward pathways. ADHD is just one of many areas in medicine I see this happening.

A lot of my opinion also hinges on that last D, disorder. For example, many people have autistic characteristics, but few have autistic spectrum disorder that severely impairs their normal functioning in life. Likewise with ADHD; just because you can’t concentrate well doesn’t mean you have a disorder. Pills shouldn’t be the first line response.

In general I see this as an issue with healthcare in general; few want to put in the hard work, everyone wants pills or injections. This is also seen in fat loss (GLP-1 drugs rather than a healthy diet and being active) or how the VA treats disabled servicemembers (pills first, skimp on the mental health treatment or physical therapy). I’m not sure where to place the crazy rise of testosterone replacement therapy but I also believe it fits in this general “drugs first” approach. We love our drugs.

The fact doctors rely heavily on patient satisfaction scores exacerbates the issue. Sometimes the best medicine is not at all what the patient wants to hear.

ADHD is massively over diagnosed in the US. No shit stimulants make you concentrate better, that doesn’t mean you had ADHD. Concentration is like a muscle, you have to actively invest effort into making it better. It’s hard to concentrate and scrolling through posts and flicking through shorts is atrophying this ability. It’s like someone who doesn’t work out or eat well thinking they have a muscle development disorder, taking anabolic steroids, and since they gained muscle it confirms their suspicions that they had a disorder. Concentrating is difficult, it takes active effort, and you will hit walls when your brain is tired. It can be trained, however. This should be the focus and stimulants should be the absolute last option and only for people who truly meet the definition of disorder, i.e. it greatly impairs their relationships, work, or daily life.

I’m not saying it doesn’t exist at all, but I do think it’s way over diagnosed. Doctors want those high patient satisfaction scores, which is another issue in medicine in general.

With enough energy you certainly could, even if that meant breaking everything down to their constituent parts chemically and doing stuff like reconstructing proteins from amino acids. This isn’t reversing entropy but you could get back to the original ingredients, with some Ship of Theseus stuff happening with the matter involved.

That’s a great question.

At first I thought it’d be a wash. The heat absorbed by vaporizing the water in the swamp cooler will be released onto the evaporator coils of the AC, so that’s a net zero energy transfer.

However, air is not good at conducting heat. This water evaporation/condensation cycle might transfer heat from the air to the evaporator coils of the AC better.

You are going to have additional water and electricity costs from running the swamp cooler though, so I really don’t know. I suppose you could run the condensation from the AC back to the swamp cooler to greatly reduce water usage.

They’re both about price in my opinion.

Personally I don’t feel the console itself is that bad, but $80 Nintendo games, that never go on sale, can fuck right off.

There’s no point as a swamp cooler does not have heat to reject. A heat pump in a traditional AC works by making one side hot (outside) and one side cool (inside). A swamp cooler decreases temps by evaporating water, which absorbs energy.

Also, swamp coolers are only effective in very dry environments. Unless you’re in the desert it’s going to make it feel warmer by raising humidity significantly. A large part of why AC makes it feel nicer is reducing humidity, which allows sweat to work better.

Fuck water, bread plus water.

The quantity of radioactive material and what form of radiation it emits is extremely relevant to this discussion.

We have seen nuclear batteries - it’s decades old technology at this point. They were used in pacemakers. They stopped in the 80s because it’s too expensive and dangerous. You have to track radiation sources like this.

In smoke detectors and tritium watches the quantity of radioactive material is minuscule compared to the beta emitter in the battery, as in multiple orders of magnitude less. None of the things you mentioned have radioactive material in any significant quantity. If you swallowed or inhaled this battery you’d be exposed to significant amounts of radiation.

A microwave is not an ionizing radiation source.
