My older brother is a product developer for a multinational food company. They send him all over the world looking for new foods and flavors. My first video upload tells about his passion for food and what he found on a recent trip to Mexico. You can see me in this video if you look real closely when he talks about growing up in Africa.

Your brother has a great job! Just ask him to speak more slowly for the camera so the audience can fully understand what he’s saying.
I was thinking the same thing. Now that I have a non-family member who agrees with me I can tell him that next time I see him!
