From Innovation to Awareness: The Rise and Fall of Leaded Gasoline
Curiosity is what drives exploration and it’s the spark that makes me stop, look around, and ask questions. If you’ve ever wondered about something as ordinary as the leaded gas pump, you’re touching on a fascinating (and troubling) piece of 20th-century history.

But what holds me the longest is not the landscape itself, but the traces of people who came before and the moments […]

It was curiosity that led me there. Every day, on my drive to Wellesley Chiropractic Office, I noticed a small British flag beside a marker in the middle of an island. What was a British flag doing in the suburbs of MA? My first assumption was a simple one: perhaps it marked a site from colonial […]
