Some years back I took a friend skiing for the first time. She fell getting off the chair lift, smacked her head pretty hard but said she was okay and skied the rest of the day...the next day was on the hospital with a severe concussion and subdural hematoma. Thankfully she recovered.

Absolutely- but you knew it happened at onset. Purely conjecture for Saget.
