Countries outside the US don’t see it as an enemy, but as a wealthy partner. Having that partner suddenly go insane and lashing out at its friends due to a malignant brain tumour is sad to see. They might well support surgery to remove the tumour in the hope that their former partner can one day recover.
It’s a bit complicated, both because some studies just asked people if they are ‘natural redheads’ and didn’t actually test whether they have the MCR1 mutation and because it depends on the mechanism of action of the drug. Some sedatives are less effective, so need higher doses, but the majority of opioid based pain control drugs require lower doses in redheads.
Redheads need a lower opioid dose than the general population to achieve the same effect. At least those who are redheads because of a mutation in their MCR1 gene, which is about 75%, IIRC. Interestingly, the same mutation group also have worse tolerance of cold, which seems odd given that scotland is the global redhead centre!
Yeah, it’s been pretty universal in the UK for at least the last couple of years. Not sure where this idea came from.
Sure it does, but most countries see the US as an ally and a valuable trading partner.
