There's a trolley, but no one is one the tracks. Do you:
a) Allow the trolley to pass by without incident, and thus rob the medical industry of its paycheck for stitching you back up
or
b) Jump in front of the trolley and get injured, but thus also delay its arrival to its destination and thus rob the trolley company shareholders of profits due to missing customers
I hate it when I accidentally commit genocide after getting cozy on the couch.
