We all need a break after few weeks or a month as there are no hard and fast rules about when you should go for a holiday. Even if you think that you are perfectly alright, you should take some time off from work so that your body parts can relax.
One needs to take a break every now and then from the stresses of work. It is highly imperative to know the value of rest and relax our body, as without it, it would start to deteriorate and fail to deal with the demands of time.
