I'm so bad at painting, I go through 2 full cans in one session. I guess the build up is happening, but I never know when to stop and clean it. By that point I've inhaled so much paint I'm seeing stars. Last time, I woke up the next day and had shingles on my face. Not related, probably, but maybe I'm so bad at painting I gave myself shingles?
Sidenote, shingles is no joke. I almost died in a motorcycle accident 4 years ago, and the pain from shingles was worse than that.
