Regular exercise is the key to good health. Try and squeeze in 30 minutes of walking during work hours. This can easily been done by walking a full 30 minutes during lunch or breaks. If you don't have 30 minutes to spare, no problem, try walking 15 minutes in the morning and evening.
Who is responsible for work safety? Everyone.
Assess your work area for possible hazards that may cause harm.
