Hey, that's MY watch! Congrats and enjoy it.
You wouldn't want my heartbeat, I have a murmur.
Sidebar story: My friend got her Apple Watch on Friday, set it up while on her lunch break. After work she went to a friends and showed it to her. When she got home she was going to watch the guided tours and set up Activity, Workout, etc. She was almost out of battery and was going to charge it while watching on her home computer. We had a big storm yesterday evening, hit at her house and out went her power. No more playing with the Apple Watch.
