See, for me that’s not too bad, as it’s disembodied. My squeamishness stops when things become ‘offal’
Blood also doesn’t bother me as I once put my textile arts skills to work giving myself 5 stitches in my ankle. Amazingly didn’t go septic (but it is not a neat scar)
As mentioned in the glasses thread, my friend reused some dirty one day contacts and gave himself a parasite, and didn’t realise the problem for too long and it got worse and worse. I went to visit him in hospital and I had to say to him that with all due respect I was there for him but couldn’t look in to his eye (he wore a patch most of the time, but when he took it off it was full zombie)
