Well how do we know that any scale at all is right?
My lab has weights that get calibrated against a NIST standard annually. We use those weights to perform daily quality control that our scale is accurate (to +/- 0.01g). If the quality control fails then we recalibrate the scale.
Early in my career, I picked up as much overtime as I could at the hospital. I worked 13 days in a row with three of the those days being 12 hour shifts. My coworkers informed that I was a real bitch after day 7 and it would be better for all of us if I didn’t work more than seven days in a row.
I took their words to heart. There’s working hard to get ahead and then there is killing yourself and making everyone around you miserable.
Retoin, won’t you retoin my love?
My love is yours
