(1) Scientific evidence has shown that hard-working people live longer in comparison. This is because it keeps them engaged and distracts them from loneliness as people come into contact with each other. It also gives a sense of fulfillment.
(2) I agree that hard work often leads to happiness in life. It is in work and discipline that people are able to find fulfillment, as they are actively working towards a goal. Take my friend Xiao Ming for example, he manages to cope with both school work and recreaction simply by managing his time well. This, I believe, is an example to be followed. I believe that there is a time for work and a time for play, when the priorities are in order and managed properly, both can be preserved.
