Scary that even a not-switched-on MRI can have that effect on machinery.
By chance, my only experience of an MRI scan, for a research study into hypoglycaemia, led to a nice experience this week. I had to go to hospital for an investigation test (which seems to have confirmed no additional problem, bt the way). A doctor (dealing with another patient) and I recognised each other - she'd been involved in the study. So, naturally, she asked what I was doing there, and when I explained the story, she confirmed my thoughts that the slightly odd blood test was probably due to running or something - she remembered that I couldn't do the 2nd part of the study, due to orienteering earlier in the day, but they hadn't said no running, and it was a very norml thing for me to do on a Wednesday evening. Anyway, we're still waiting for MRI time to complete the study. An unexpected benefit for me to see a familiar face, in addition to other helpful friendly competent staff, just because I'd volunteered for a research study.
