If you are the type of person who has always felt like you needed an excuse, a way to justify the activity, today is your last chance to go at with wild abandon; with immunity. Enjoy it to your fullest extent. Maybe really take your time, edge it out for a few hours to really savor the sensations. Build it to a thundering crescendo that can no longer be held back.
Then kick back and chill out...
...with that satisfied smile on your face.
You (and you arms) deserve a rest.
