Was thinking about this. When I was a kid I used to tease my dad mercilessly when he complained he couldn't eat McDonalds (he actually had some pretty serious intestinal issues) but as I got older I realized that a lot of stuff just doesn't go thru as easily as when you are younger.I found out yesterday that I cannot eat a Big Mac for lunch, and then go to the Red Eye brewery and eat one of their hamburgers , too. I suffered until 5 AM trying to get to sleep. too much meat..
