So You Got A Scientist, Part II: Maintenance

It may happen that occasionally your scientist will forget to shower. That morning he may have become fascinated by something he saw on the wall or thought of on the toilet--he's not actively trying to annoy anyone--and neglected certain basics. If this occurs, have someone (not a wine lover) engage the scientist in conversation and suggest that they build an artifical nose to alert them when a shower is needed. This artificial nose should be calibrated against real noses, starting that day.

You might imagine that the scientist will get the hint and make a point of bathing. No. Scientists do not get hints. They do, however, build things, and there is a fair chance that yours will actually build an artificial nose. Problem solved.
