I'll just repeat what everyone else is saying.
Most of the posts on here are people concerned about their beardies. Most of the time, it's normal behavior, or something the owner has been doing incorrectly, such as not having the correct lighting or substrate. If you read these forums for information and give your beardie the proper care; feeding, lighting, substrate, and most importantly, attention, you should have a healthy beardie. Also, very important that you buy your beardie from a breeder, or a good, responsible, reptile shop. Beardies from Petsmart (and other major pet stores) are knows to come with problems because of improper housing and care.
Of course, sometimes, even with the best possible care, your beardie may get sick. But that's what we're here for.
I will tell you that I have a very healthy active beardie. He never had relocation stress, never been sick, eats like it's going out of style, and loves cuddles and attention.
