They speculated that immune systems evolved to avoid being continuously on alert. And that's exactly right- our immune systems have an extremely complicated system for detecting foreign invaders that is tightly regulated. And a failure to regulate that is often associated with autoimmune disorders, which remain very poorly understood.

I've studied biology from the perspective of engineering better drugs for decades now and I can say with confidence that I simply don't understand how the immune system works, and I don't think anybody else really does either (compared to, say, the heart, or many biological systems like protein production). We have identified many players, and observed a great deal of actions, and have speculative models for many of the underlying processes, but we don't really have an "understanding" of the immune system. I skimmed this paper and frankly, it has a very long way to go before people are convinced to try this in human clinical trials.

I look forward to innovations, but to a first order approximation: evolution found model parameters that exceed the best human science and engineering.

This is just an idiom for denoting a high alert state.

"Sorry son, you can't get these glasses. It's for the betterment of humanity."

Remember that cephalopod brains are donut shaped and their digestive tracts go right through the middle and if they eat something too big they'll have an anyeurism. Pandas and koalas evolved special diets that serve no evolutionary purpose and both would be extinct if humans didn't find them cute. Sloths have to climb down from trees to take a shit. Female hyenas give birth through a pseudopenis that often ruptures and kils them. Horses can't vomit and if they swallow something toxic, their stomach ruptures. Also their hooves and ankles are extremely weak and not well designed to support their weight. Numerous species like the fiddler crab and peacock have evolved sexual displays that are actively harmful to their survival.

And as for humans, our spines are not well adapted for walking upright, our retinas are wired backwards, and we still have a useless appendix and wisdom teeth. The recurrent laryngeal nerve has an unnecessarily long and complex route branching off the vagus and travelling around the aorta before running back up to the larynx.

Evolution is not smart. Evolution isn't even stupid. It isn't trying to keep you alive and it isn't even capable of caring if you die. Yes we should absolutely fuck with it, because we don't want to live in a world where we still die of sepsis and parasites and plagues because "we don't want to mess with evolution."

Now, you could have restated this in a better way IMHO. I'd put it like this: are there any evolutionary advantages to having worse-than-average near or far vision? For example, we can imagine that people who had extremely good long range vision would be more successful in hunting, and perhaps- this is where I'm speculating heavily- having poor long vision is compensated by having better detail vision for fine tool work. However, what I've learned after many years is that attempting to perceive the true nature of the evolutionary fitness function is challenging.

As for your bit about suicide: please be a lot more thoughtful in speculating about suicide.

The treatment also supposedly activates macrophages in the lungs (and thus not elsewhere). Only some small particles and vapor droplets from foods go into the lungs.

>There may also be consequences to dialling up the immune system beyond its normal state – raising questions of immune disorders.

> Jonathan Ball, professor of molecular virology at the Liverpool School of Tropical Medicine, said the work was undeniably "exciting" but cautioned "we have to ensure that keeping the body on 'high alert' doesn't lead to friendly fire, where a hyper-ready immune system accidentally triggers unwelcome side effects".

> The research team in the US does not think the immune system should be permanently dialled up and think such a vaccine should be used to compliment rather than replace current vaccines.

The body is like legacy spaghetti code written by hundreds of teams of outsourced engineers. It mostly works. Just never remove any commented out lines or it may break.
