Hi Mich, hope you are doing ok and liked that you found my story :)
Exercise? Well, as I said, I took the dog out every day and I'm all for it. It helps you stay normal to stick to a bit of a routine (not that I'm at all routine driven!) but also I found it helped with digestion and it just made me happy. Even on really cold days, the sky was blue and people's gardens were changing every day. I'd meet folk out walking to and say hi or stop for a chat. I gardened as well. Nothing taxing but I've got big gardens and you do that because you love it.. Everyone is different so it's really up to you but it certainly helped me.
