A LOT going on this year.
First, all time record low temperatures are expected. It'll be the coldest olympics ever.
Second, South Korea is trashing their chance of medals by hosting unified Korea teams. The North Korean members are less strong, less trained, and joined at the last minute. But South Korea hopes it's worth it. Despite this there are South Korean protestors to the move.
Norovirus may be a big issue at these games - its going around.
Jamaican and African winter teams galore! Many for the first time ever. We'll see the first African skeleton competer, from Ghana. The famous Jamaican bobsled team is back, and has added a women's team! Also the first Nigerian bobsled team is on, and it's also the first African bobsled team.
