There's no smoke without fire
There's no smoke without fire
Actually, there can be - Many materials will smoke before reaching their ignition temperature (flash point). If oxygen is low , some material (fuels) will smoke heavily without igniting. The smoke that results can be extremely combustible and will burn violently when oxygen is introduced. This is what causes backdrafts in fires within structures.

The sun!
Without the sun which is very much on fire none of that would be possible

The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together...and release some energy as well. This energy then heats up the other materials (other protons and electrons and such) nearby. This heating eventually grows out from the center (or core) of the star to the outside, finally leaving the surface and radiating out into space to be the heat and light we know stars emit.
People, including scientists, sometimes say that the Sun "burns hydrogen" to make it glow. But that is just a figure of speech. Hydrogen really doesn't burn, it fuses, into helium. So no oxygen is required!

In that case sun " burn " is a complete myth , so to prevent extreme redness coupled with blisters and considerable pain we should be applying proton collision factor 30.
Strictly speaking it's actually a radiation burn that results from an overexposure to ultraviolet (UV) radiation from the sun.
Moderate sun tanning without burning can also prevent subsequent sunburn, as it increases the amount of melanin, the pigment that is the skin's natural defense against overexposure.
When the skin cells DNA is too badly damaged by UV radiation, cell-death is triggered and the skin is replaced - hence peeling skin

Has he quit yet? He does have a tendency to have a meltdown when things aren't going his way.
Seriously though, he ain't leaving is he? A year outside the PL doing all those ****ty mid-week slogs just to walk away when there's 2 months left of a transfer window to go.
