Cold Steak with Lots of Salt

Cold steak with lots of salt prior to donating blood (maybe... if I pass the height/weight test!).
Going to try to donate blood today for the first time since I was in university in the 70s. It didn't go well back then, but I feel confident I will be okay now.
However, they have a height/weight restriction and I barely make it in! At 5' 5" you have to be at least 115 pounds. I weigh 117 pounds. Yikes! At 5' 4" you have to be 120 pounds! I think I'm somewhere in between height-wise, but not sure of my exact height anymore, so we'll see what happens. I may get rejected!
