A belated update.
So... about 30 days ago I was merrily ripping down my favorite ski slope when a (checks notes on how to be polite) rather clueless individual cut across the line of travel without looking. My buddy I was skiing with narrowly avoided the guy... I didn't luck out as much, had to slam on the brakes, hit ice that wouldn't have been an issue had I not needed to brake hard, and went down HARD. Big crash, slammed my head really bad, was out for around 30 seconds.
Next few hours were kinda a blur. Snowmobile ride down the mountain. ER for a few hours. Nurse saying I likely wouldn't be alive were it not for my fancy MIPS helmet (safety tech is good yo!) Extremely painful drive home. Lying on the couch for 48 hours.
Finally starting to resume normal life a few days later. Doctors visits. Tracers at night... which then went away! Being able to drive again. Finding out I can ride my bike again 4 weeks after the concussion, which was a big win.
Fast forward to now and I'm finally back at it! Definitely still have some lingering effects with paying attention and whatnot, but feeling a lot better and healing well.
Lessons learned here? I dunno. Probably will ski a little slower in the future but accidents happen and it was a genuine mistake on the part of the guy who caused me to crash so all good there. Very glad to have the right safety equipment and I'll never ski or ride without a helmet, that's for sure. But at the same time I'm mostly happy to have healed and be back at it!
