I have 2 disks out in my lower back, but I find as long as I exercise and walk I am OK. If not, I have terrible pain down my left leg and spazums in my lower back, which, according to a Ortho. Surgeon, is from pressure being put on my sciatic nerve from extra weight. How is that for a motivation for you? I am a walker as my user name implies. I walk about 5-7 miles a day..today 5. I need to stay healthy for more than just wanting to look good on vacation or fit into a certain dress. I do it so I am not in constant pain. I was watching the Dr. Oz show on Obesity yesterday, and I came to realize that when I was 45 pounds heavier, not only was my back and legs in pain, but my inside organs were as well. Just because we can't see the damage inside, doesn't mean it isn't there. We all need to realize that this being healthy isn't a "just for now" thing to do. IT is a choice we are all making...to live longer and get the most out of life that we can, make happy memories at Disney and in all parts of our lives.
