  1. Hi Scott,
    Thanks for your comment.
    I’ve been inspired by a lot of people who’ve chosen a plant based diet recently. Just thought I’d research who else in the public eye has made the same decision and how it has impacted their world. Hoping others might be inspired to make a positive change in their lives, as well.
    Hope you have a great day!
