When I was in Canada (I left two weeks ago) I took Vit D daily. Now I am taking less but walking on the beach for an hour or two every day.

Both my wife and I are in such better spirits. We spent three months from Jan to Apr stuck at home, in Quebec, cold and with little to do. I am convinced the shut downs do little (except perhaps help the virus spread indoors). Mental health is certainly not helped by either winter or staying inside.
