'Duder' Mags? I like that. When I asked for my little finger to be amputated (as was then, the recommended next step, but they changed their minds) I asked to watch that. It helps, to see the process through. I do the same now with needles, or did- when recaching my goal of donating an equivalent amount of blood products back to Red Cross I used (which I did).
That is on hold at the mo- as surgical procedures are a thing they watch in donating. I have a kids fake tattoo sticker (backwards with backing on it) quietly on display and hard to notice on the rear window of my car that reads 'bloody legend'. They gave it to me after my 10th successful donation (15 visits- 5 no go's).
