I am new here and need help

I used to be a Medic and Firefighter-- in short I was an adrenaline junkie. And now I'm old and retired. And my body is bent and currently a bit broken. I seek to learn how to be dull.

Despite the enjoyment of watching the hummingbirds at my feeders and the light gardening I do. I still think I could become even more satisfied with my dullness.

Guide me to complete dullness!
