You weren’t belaying him climbing and dropped him (has happened)

You didn’t shoot him by accident

You didn’t run into him

if he said ‘stop forcing me to do this’ then you might feel bad, rightly

Otherwise, it seems to be an accident

re prognosis – incredibly individual – from what you describe – could be 100% recovery (like me) to long impairment (like a friend) – it’s so difficult to know until end of first month …

but being in good hospital is vital

was he wearing helmet? MIPS?

People are odd. We’ve found quite remarkable things being thrown out. Parents empty bedrooms of their student offspring etc. students leave remarkable good bikes to waste after they leave university – one of my colleagues has a penchant for the bottle and after a heavy night on the town entirely forgot where they left their bike – just shrugged and said nope no idea – but doing a check in the database above is good plus well done for posting here.
