Hi Bob, read a couple of your blogs today and wondered if you had considered any particular hobbies. Since you have a medical background I was thinking sciences, natural ones and those to do with following anthropological or archaeological things perhaps as they often intertwine. Like ancient persons and cultures if you never thought of it before , it might be of interest to you. Also reasonable herbal medicine knowledge. Foraging for them and edibles, as long as you stay with strictly safe easy to identify ones is alot of fun and can be part of an occasional meal. There may be at least half a dozen growing around where you have your horses !
