Don't slouch!

Find yourself getting tired easily when using your PC? It might be that you're in an uncomfortable environment.Make sure that you use a chair with good lumbar support,that you have sufficient place to rest your palms and that your eyes are aligned to the top of your monitor and at least 45cm away - these tips allow you to sit comfortably with reduced strain on your back,arms and neck.Oh,and make sure your room is brightly lit and that you're not sitting with your back to a window - this reduces glare and keeps your eyes happy.
