Ecommerce and back pain

Thankfully with ecommerce I can continue working even with back pain. Went to lift over 1kg last night wish is a push at the best of times and felt my back go :) so much so the strong man competition this year. I will stick to ecommerce development and SEO for fun. Tried using a ball to sit on when typing and it seems to ease the pain, so for all ecommerce web designers out there, get yourselves a ball to sit on as it helps ecommerce posture and prevents injuries like mine :(
