I always imagined Dagny as a soprano, not a bass.
Not a criticism, I was just startled by how low her voice is.
She appears to have accomplished a great deal in the medical testing industry.

"the Fortune mag article on her-
dropped out college at 19 to start her business and is a billionaire. She is Dagny "
Yes!
I love the whole story.
She comes off as if it never occurred to her to be arrogant or to bellyache about all the difficulties one must overcome to become a billionaire.
I like the way the host spent two minutes asking her why she isn't looking for equity funding. She kept saying she wants to grow organically. The finance world expects her to take it public, and then they'll find a CEO experienced with larger organizations. Instead she's staying with it, keeping her equity, and growing organically. Way to go for this CEO/founder..

yes, and easy on the eyes to boot. let's hope her patents aren't revoked as medical diagnostic patents are facing in the current environment
