My co-worker was out on his noon ride but came back an hour late. His friend was there when he arrived and asked him what on earth happened as his helmet was all smashed up and his side was all road-rashed. He didn't know what happened. He lost an hour. He has no memory of what happened before, what happened to get him all smashed up or how he got back to work an hour later.
Really weird. I don't know what there is to discuss about that, but I had to tell somebody. Hit and run? I hope not. Who'd leave somebody unconscious by the side of the road? Or was he unconscious? Maybe he was semi-conscious and sat by the side of the road for an hour? Who knows. He had an MRI and CAT scan and nothing is wrong, thankfully.
