CV and mad panic behaviour

[PaulP]

That Wikipedia page you referenced earlier exposes a partial hint at a reason for this, it's possibly related to vasovagal syncope and differentiated from Aichmophobia(fear of sharps) compared to Trypanophobia(fear of injections).

So I suspect a person may well tolerate sharp things like pin pricks of a tattoo, but an intravenous needle might still trigger an involuntary syncope.

I suppose it seems irrational to unaffected 3rd parties, but I suspect given we are discussing this in context of a vaccine and 5G conspiracy association it probably makes perfect sense.

I guess that seems reasonable.
