Aren't you darling? You're going to be gangbusters.

Here are some tips from MayoClinic.com to keeping proper posture and preventing painful back problems by maintaining healthy work environments:

Proper Typing Posture

When seated, there are a few tips you can use to be sure you have the best posture.

• Choose a chair that allows you to rest both feet flat on the floor, while keeping knees level to your hips. Use a foot stool if you must.
• Sit with your back firmly against your chair. If you need to, use a cushion or rolled towel behind the curve of your back.
• Stretch the top of your head toward the ceiling and tuck your chin in slightly.
• Keep your upper back and neck comfortably straight.
• Keep your shoulders relaxed- not elevated, rounded or pulled backward.

Adapt Your Work Environment

• Plan Your Moves. Reorganize your work to eliminate high-risk, repetitive movements. 
• Listen to Your Body. If you must sit for a long time, change your position often. Try tricks like standing when you answer the phone, or stretching periodically.
