Here are mine:
- Following a big meal
- When my wife rubs or massages my back
- Reading a good book
- Right after sex
- Playing with pets, mainly cats
- Taking a hot shower
- Hearing someone who has a very mellow voice, like painter Bob Ross
- Sunbathing on the beach, especially if I can hear waves gently lapping the sand
I'm sure I've missed a few.
Do you agree with some or all of these? What would your list include?
