Did anybody bring up Fish Tanks?? I read that if you sit and watch fish swimming it calms your heart rate.. I had tanks before and the sound of the pump kinda humming sitting there watching the fish as they get right up to the glass as if to say.. "Hey.. Where the food Bub"??? It's cool..
But long walks are really relaxing. Just sitting outside on a warm day taking deep breaths and listening to the earth. Oh ya.. My favorite.. Go to the beach and sit and listen to the surf. I always said it sounds like Mother Earth Breathing..
