Serious answer, the earth's magnetic field weakening is accelerating [1] [2].
It began declining in 1859 [3] but the changes have increased in recent times, with the magnetic pole shifting significantly such that even airport runways had to be renumbered [4].
The weakening geomagnetic field leaves earth more vulnerable [5] to inclement space weather [6].
It has been shown in mice, the negative behavioral effects of increased space radiation [7]:
"Studies in murine models have shown that exposure to high-energy 56Fe particles, which are the largest effective dose contributor in the space radiation environment, impairs cognitive function. These impairments include deficits in spatial learning and memory, object recognition, and operant conditioning, which parallel the cognitive decline observed in aged animals. [...] These behavioural studies, taken together with investigations into low dose HZE radiation effects on neurons and neural tissue, illustrate the risks that space radiation may pose to human health."
and [8]:
"Acute and chronic tissue alterations arise from the damaging effects of highly energetic charged particles that penetrate the spacecraft and traverse though the tissues of the body. These fully ionized nuclei are derived chiefly from solar ejection events (e.g. protons) or galactic cosmic rays (GCR) composed of light and heavy ions (Z from 1 to 26)
Past work with rodents has demonstrated that whole body and/or brain exposure to charged particles can elicit various behavioral decrements that can be linked to impairments in the hippocampus, amygdala, basal forebrain, medial prefrontal cortex (mPFC), and other brain domains."
If this model holds true, we can expect things to get worse and worse at an increasing rate in the coming years/decades until the field strengthens.

Thanks for this list. This may be useful for those interested in Nassim Nicholas Taleb's dietary practice to "only eat that which our ancestors ate 1000 years ago", aka the antifragile diet.
Among the oldest, no surprises to paleo/ancestral/traditional:
American bison---8,000BC
pigs, goats & sheep---7,000BC
lard---7,000BC
cattle domestication---6,500BC
milk & yogurt, & sour cream---5000BC
...but at the other end, these foods were older than I had expected, still over a thousand years ago (!):
American-style beef jerky is almost invariably sweetened, unfortunately.
I ran into this same problem, but found a slightly different product without sugar:
South African-style beef jerky, known as "biltong" - it is also a spiced dried meat, but is more meatier and almost always unsweetened.
Biltong can be found at specialty/ethnic food stores, my local grocery shops carry it but display it separately from the American jerky, you have to know where to look (or order online), but it is worth it.
Or, it is easy enough to make jerky at home if you have a dehydrator - slice strips of lean beef (I've used top round, bottom round, eye of round, and tenderloin), cover with salt/pepper and/or spices to taste, then dehydrate overnight for a tasty sugar-free treat.

> Abstract: Multi-disciplinary research has revealed that electrically conductive contact of the human body with the surface of the Earth (grounding or earthing) produces intriguing effects on physiology and health. Such effects relate to inflammation, immune responses, wound healing, and prevention and treatment of chronic inflammatory and autoimmune diseases. The purpose of this report is two-fold: to 1) inform researchers about what appears to be a new perspective to the study of inflammation, and 2) alert researchers that the length of time and degree (resistance to ground) of grounding of experimental animals is an important but usually overlooked factor that can influence outcomes of studies of inflammation, wound healing, and tumorigenesis. Specifically, grounding an organism produces measurable differences in the concentrations of white blood cells, cytokines, and other molecules involved in the inflammatory response. We present several hypotheses to explain observed effects, based on current research results and our understanding of the electronic aspects of cell and tissue physiology, cell biology, biophysics, and biochemistry.
> Since you don't have eyes sensitive to the EM wavelength of Wi-Fi, you can't shine a 'wifi light' too brightly next to you.
This is dangerously wrong. Vision damage is not prevented by the wavelength not being in the visible spectrum. Even if you can't see it, and even if it is non-ionizing, electromagnetic waves still impart energy.
Eyes cannot efficiently dissipate heat, so sufficiently strong EMF will damage the eye. This is a well-known risk when operating with strong microwave signals, for example.

> Most of the early research was carried out in the lower portion of the microwave spectrum (at 2.45 GHz) and demonstrated a high dose response relationship between microwave exposure and cataract induction. For example, Carpenter and Van Ummersen irradiated anesthetized rabbits at 2.45 GHz and showed a decreasing threshold for cataractogenesis from 4 minute exposure at 400 mW/cm2 to 40 minutes at 80 mW/cm2• Guy et al. ... repeated some of the earlier research and found essentially the same threshold for cataract production in rabbits exposed with a near field applicator at 2.45 GHz. At minimum, they determined that 150 mW/cm2 was required for 100 min to produce a cataract.
Not saying your Wi-Fi router is going to cause cataracts, but don't think just because you can't see something it can't hurt your vision. In fact, it could be argued invisibly strong EMF is _more_ dangerous than visible light because it doesn't trigger the self-protective blink reflex.
