It is not the responsibility of everyone else to ensure that absolutely no harm comes to anyone else. At some point we have to say, this is your responsibility to ensure that it doesn't kill you. Extreme reactions that are stupidly rare in society is one of these times.

We cannot cocoon society so that no harm comes to anyone, anywhere. That will, ironically, do more harm than good.

Really, if you have to inconvenience 300+ people, it's time to admit that the activity is not for you.

Blimey. Remind me not to step out on a zebra crossing in front of you.

The irony is that both keys were doing it so I gave each a new battery, Duracell no less. Now they are both unreliable when cold.

Do tac switches go inefficient when cold. Or it could be the rubbery key bodies?

Batteries rely on chemical reactions, cold weather impacts the speed of those reactions.

This. The reaction rate at 0C is significantly lower than at 20C, so warming up your keys will allow the battery to work properly.

Why are there always old tyres tied to the sides of cattle grids?

I would guess it's to stop animals trying to get past the cattle grid.

Because new ones cost a fair bit and are better suited to use on motor vehicles.

A couple of very random ones from me:

1. We can have blue, brown or green eyes, or variations of those colours. Why no red/orange eyes?

2. Why do scarves always have "tassles" at the end, as if they haven't been finished? When was it decided that this was a good look?

I told you they were random!

We only have melanin as the source of pigment in our eyes, so the colour is determined by how much melanin is released and then the scattering of that light within the iris

Other species have other pigments available as well, but we do not.

I'm sure you're right, but how on earth do you know that?

not all scarves have tassles

Mr Stephens, GCSE biology, had eyes of different colours and explained why, and I remember it well as he explained that melanin was also the reason that I have considerably higher number of moles on my skin than normal people.

From one of the Jimmy threads,

Why are some colours of some cats not available in some countries? I get things like engines or transmissions that would affect emmisions or different aerodynamic options, but some things are strange. The colour surely would affect type approval!

Why ?

What's a jimmy thread ? And you threw me for a moment there referring to cats !

Was the motor insurance sector set up solely to provide employment to utter aholes?

No.

It was in tough competition with estate agents, recruitment consultants and car salesmen.

If I’m in an elevator thats plummeting and going to hit the floor at 80mph but just before it hits the ground I jump upward at 80mph, what speed do I hit the floor at please ?

At a negligible speed, having gone from 80mph to zero miles an hour, and then accelerated a very short distance to the floor of the crashed lift.

Sadly, jumping at 80mph is not on the cards. What would actually happen is you’d hit the floor of the crashed lift at about 77 mph and die.

The force required to accelerate you that fast is roughly the same force as you'd experience from crashing into the floor. Either way you're fked.
