If you’re trying to figure out whether someone has a fake smile, look at their eyes. When you have a genuine smile, the corners of your mouth upturn, your cheeks raise, and the skin around your eyes crinkles. Known as the ‘Duchenne smile’, it happens involuntarily when you’re truly happy about something- so a smile without eye crinkles is a good indicator that it’s forced or fake. (, , )

Cruise ships have their own morgues. Roughly 200 people die on cruise ships each year, especially on those that carry a lot of seniors, so most ships have a small morgue on board and are prepared to store up to 10 bodies. (, , )
