So how did we end up driving away from the hospital feeling like a pair of geriatrics? Walking home this morning, Jenny decided to do a random tensile test on the pavement. With her head. It would appear the footpath, comprising several layers of concrete & tarmacadem is just as hard as you would expect and afterwards showed no visible signs of her crash landing on it. Apart from the blood that is. Anyway, looking on the bright side, at least the emergency services, when they arrived, didn't have to draw chalk lines around her.
