Buller Buller  asked the Naked Scientists:
   
Just wanted to ask the naked scientist why is it that those of us who have surgical operations feel pain when it is cloudy.


I feel pains when the stars are concentrated in the sky, when the moon is full and when it is cloudy.

Secondly, why is that when a dog tries to poo and I lock my pinkie finger with someone elses and pull like in a tug of war, the dog fails to drop.

Thank you
Sello

What do you think?

I feel pains when the stars are concentrated in the sky, when the moon is full

i.e. outdoors at night when the sky is clear, i.e. scar hurts when the air is cold.
Scar tissue can have subnormal blood circulation, the circulation becomes even poorer when it is cold.

... why is that when a dog tries to poo and I lock my pinkie finger with someone elses and pull like in a tug of war, the dog fails to drop.

Maybe the dog thinks a member of its pack (you) is under attack.
Defending itself, and maybe you, from an attacker would take priority over having a dump.
