Toilet Seat Science

Is there a more crucial couple's decision than who of the two must lift and/or lower the connubial toilet seat?

Some wanton women try to toilet train men into lifting and lowering each visit. And the insolent males spray the seat with indifference leading to a nasty surprise for her in the middle of the night.

So what's the straddling strategy equitable to both side?

Michigan State U professor Jay Pil Choi did the math: the best way to minimize effort for either party is to leave the seat in the position last used.
