First of all, have you ever driven a scooter? The things are horrendously slow. Also, when you release to brake, the brake doesn't enact for about 3 inches. I use an electric wheelchair and have learned to brake fast by jerking back on my throttle. And uh how many times did you or the person you saw, cut off the person in the scooter because it was going too slow??? I know that every time we have gone to WDW (4 wheelchairs) people will look us in the eye and then try to cut through. Some of my favorite tricks are when they link arms or the best-they literally shove their small child in front of me causing me to swerve or stop suddenly. You know how many times that I have been run into because someone had their head turned talking while walking and practically fell on me?? I always have to be attentive, watching for the rude, ignorant, or wandering toddlers. Our family has to form a little train to get anywhere. Anyway, on to your original question. Off my soap box, I am trying to be understanding as I can see that you would be irritated since you have not been enlightened. I study health problems as a hobby so here goes.
1. Some medicines cause you to gain weight or appear overweight. These medicines are used to treat life-threatening conditions. Prednisone is one.
2. If you have some muscle diseases your body cannot burn the amount of calories that it consumes. And how exactly do you exerise when you can't walk? Should you starve yourself, always hungry? Thankfully, I do not have this problem but my mom does. Doctors told her in order to lose weight she would have to have no more than 750 calories a day.
3. Many diseases like arthritis cause severe pain and stiffness. Ever tried exercising with sprained ankles, knees, and shoulders???
4. Some disabilitie like lupus, Crohns disease, and Juvenile Rheumatoid Arthritis come in 'flares.' They may be stable one minute and in an hour have horrible fatigue and pain. They may appear 'normal.'
5. Perhaps these people want to lose weight and can't. Your judgement certainly doesn't help.
Oh, WHEELCHAIRS DON'T "CUT IN LINE." They do that because the regular lines cannot accomodate wheelchairs. There are already many attractions people in wheelchairs can't get on. Now complaints are making it difficult to get assistance. We have to arrive just as early (1-2 hrs.) for night-time shows with designated wheelchair seating to get a good spot.
Hope you understand a little better.
