Apparently Radio Frequencies, like those in Wifi reduces sperm motility in rats. Interesting how the test shows that it lowers the population of rats but not us. Or does it?

we speculate that RF-EMR from mobile phones negatively affects semen quality and may impair male fertility.

It depends on the frequency. wifi 2.12 has a different effect than the earlier 1.89....
they pale in comparison to that emitted from TV (it kills brain cells)
Bluetooth, on the other hand, is benificial...it's got higher frequency, similar to grow light for plants.
This probably deserves an entire piece of its own, in terms of how hidden dangers indirectly promote the Eugenics of those who are able to perceive them, despite what the establishment tells them.
Let's say X or Y modern lifestyle choices, foods, technologies are harmful. Companies have an interest in saying they are harmless. By the time the general population finds out it's too late - and their DNA has been damaged. Those who understood the truth prior to the establishment admitting it are thus benefited.
Certain radiowave applications, GMOs, etc could fall into such scenarios.
