Thankful Day 1 and 2

I've got to catch up with this Thankful Day stuff!
Day 1: I'm thankful for water's hydrogen bonding property. Without it, the climate on earth wouldn't be stable enough for life.
Day 2: I'm thankful for mitochondria. These little bacteria made a symbiotic pact early in eukaryotic cell evolution to provide us energy in exchange for a home.
