I’m sure many of you can relate to Jason here. I know I can, and I’m not even a pilot! But I sure know the feeling of concentrating so hard on something that at some point I start feeling the stitches and realize I probably stopped breathing a minute ago. Another, and actually more relevant risk for me is to concentrate on something work-related on the computer so intensely (usually when coding, not so much when drawing) that I forget to drink. I have a couple of bottles of mineral water besides my desk for emergency purposes, haha!
