In August of 2012 BuzzFeed reported that Oma (or grandma) Ella Kastner was the world’s oldest Facebook member. “Hello Mr. Mark Zuckerberg,” she says in a YouTube video. “I am on Facebook.” I was intrigued, so I friended her and discovered that she is remarkable, traveling all over the world even as a centenarian. Serendipitously I discovered an online travel community called Passion Passport - www.passionpassport.com - and I entered their Bucket List Initiative travel grant contest - http://passionpassport.com/current-trip/. I was chosen as a finalist, I won the contest, and then I spent eight days in Germany with Oma Ella. That lady changed my life. Here’s what I learned from her.
