Weight-loss surgery

I am absolutely floored by this. People are going to Mexico to have weight-loss surgery b/c it's less expensive and the guidelines are less stringent. Guidelines aside, the cost is the part that floors me. So people will go under the knife and have their digestive system rerouted and then deal with weird side effects for $15K to $30K or more. But they won't pay a personal trainer $150 a week (an average of $50 a session X3) to learn how to exercise efficiently and have FUN! Heck, if you get the right personal trainer, you may even get a new friend for life. I know the surgery works for a lot of people who (for whatever reason - mental blocks they can't overcome, whatever) believe they can't lose the weight any other way, but if cost is the main issue, those are some odd priorities in my humble and biased opinion.
