In a nuclear war, hundreds to thousands of detonations would occur within minutes, resulting in tens to hundreds of millions of people dead or injured in a few days. But a few years after, global climatic changes caused by the many nuclear explosions could be responsible for the death of more than half of the human population on Earth.

The loss of the Earth’s protective ozone layer would result in several years of extremely high ultraviolet (UV) light at the surface, a hazard to human health and food production. Most recent estimates indicate that the ozone loss after a global nuclear war would lead to a tropical UV index above 35, starting three years after the war and lasting for four years. The US Environmental Protection Agency considers a UV index of 11 to pose an “extreme” danger; 15 minutes of exposure to a UV index of 12 causes unprotected human skin to experience sunburn. Globally, the average sunlight in the UV-B range would increase by 20 percent. High levels of UV-B radiation are known to cause sunburn, photoaging, skin cancer, and cataracts in humans. They also inhibit the photolysis reaction required for leaf expansion and plant growth.

      Nope, sorry. The lemmy doctor’s diagnose stands.
      Please report to your nearest pharmacy for mandatory amphetamine administration.

        I would actually like to try amphetamines. I don’t get happy or excited about anything and I genuinely wonder if some ecstasy could unlock that part of my brain. Probably a bad idea, I know…

      There are at least two subtypes of ADHD with very different symptoms, so that kitchensink typically doesn’t fit anyone currently alive.

      Whether you do or do not have ADHD I would advise against recreational stimulant use. Particularly MDMA/MDA doesn’t unlock anything permanently, and can be used only infrequently without significant negative side effects.
