Avantages
Fast pace so it doesn't feel like you are there 12-15 hours when that is what it often ends up being. They will pay well for you to turn your life over to them.
Inconvénients
Say goodbye to your physical wellness. You will most likely not get breaks for lunch or any breaks at all so you end up eating crap or nothing at all. You are working so physically hard that you will continuously lose weight regardless of what you eat anyway. You are not properly fueling your body so your body may rapidly break down. Almost everyone has carpal tunnel- even if they don't know what all that "numbness" is. Arthritis, bone spurs, back pain, injuries, lack of nutrition, lack of sleep, lack of family/friend time will definitely be in your future if you choose this career path- do not doubt this even if you are going for the DM position. The trade off for the money is quite steep.
