Temperatures around the Bay Area are much cooler today than earlier this week. Are you liking the conditions today, or do you miss the heat?

Fun topic to share over breakfast. It's estimated that a single breath of air contains (10 to the 22nd power) molecules. It would take over 15,400 years for the world's population (7.7 billion people) with an average number of daily breaths (23,000) to reach that number!

Umunhum is a phrase from the Ohlone language meaning "resting place of the hummingbird". There is a ceremonial space dedicated to the Ohlone there if you are interested in learning more about the local tribes.

Q: What did the Pacific Ocean say to the SF coast? A: I'm your biggest fan. On what's not a joke is heat stress. A was issued for the N&E Bays for the 3rd day in a row. Take breaks, stay hydrated & check in others.
