A guy with a great mind until, in the mid '90s, he was set upon by a gang with scaffold poles. He was so badly beaten up & left for dead. His injuries were a fractured scull, in 3 places, 5 ribs, pelvis & leg fractures. After major life-saving surgery he spent 4 months in Intensive Care.
I used to have amazing conversations with him about the environment, land use & CC/GW, now, it's lucky to get a sentence out of him that is coherent.
