Magic glove

I popped along to the Guy's Cancer Centre for my first chemotherapy session of the new season. There was a notice apologizing for an up to two hour delay due to a "cytotoxic spillage" in the pharmacy. 
When I eventually got into the treatment area the nurse couldn't find a suitable vein (two attempts). Then another nurse arrived with this glove full of warm water - it brings up veins a treat... top tip.
Life was much easier in the good old days.
