Be wise and co-operate!

   Benefits of being co-operative, will be felt only when one feels himself/herself the loss of the companionship, incurred while being uncooperative with others!

Restricting to one's limits!

          As a person/his body ages on, he should be aware of  his own limits. And he should do activities with his body, within it's limits and to the extent of its capability only - without either overusing it or leaving it to remain idle!
