Handy tip there scruffy, am curious to see if I'll remember, or rather, need to remember it ;) My upper left arm has an assortment of scare tissue from jabs given to me during my school years. Given the years gone since then, they must have been
woppers back in the day ; I doubt today's jab will leave an impression... but it was as I was driving back to work and changing gears that the question of arms bearing the brunt came to me.
I'm a lefty always have been. And I don't ever recall being asked my preference. As my arm was covered in a three quarter sleeve, my doctor tapped me on the upper arm as he walked toward his drugs cupboard. I dutifully pulled up the sleeve without
giving it a thought - he's busy.
