I ended up getting taken to casualty 'cause my neighbours wouldn't let me not go, and it turns out I have a cracked rib and a lot of bruising. Which means I can't do much physical stuff and if there's any sharp pains I've to head straight into the hospital in case the rib grazes my lung.
I'm fine, or I will be, and the guy on the bike doesn't have a scratch on him and is insanely apologetic, but wow this hurts right now! So pedestrians? Let this be a lesson to you... actually, I have no idea what the lesson is - don't have headphones on at 6am in case a mad bike rider is on the path?
