What are the possible effects of living long on an individual and on the whole society?
Give some examples for and against according to your knowledge.

Longevity has its own advantages and disadvantages. There are some social, financial and personal effects to be considered on both individual and social level.

Positive effects of living long as an individual are getting a chance to see the family tree grow. Being able to participate in family events like weddings of grandchildren, baby showers etc. There are also some disadvantages, such as health problems, dependency etc. It becomes harder when one has no family members to take care of him. Looking from a society's perspective, it is a blessing to have elderly people in the society. The gift of their wisdom and life experiences is valuable. If practised wisely one can achieve great success. The only disadvantage can be financial burden on government and families. Government might fail to provide for senior citizen if majority of population lives long.

Now having an elderly person in house can solve many of the family's issues. A senior can look after children while parents are away for work, this can save a good amount of money. Moreover, in today's competitive world, where men suffer from stress, anxiety and depression; emotional support from parents and grandparents can be really helpful. On the other side, a person living long may have to suffer from some disease which could be a torture to the person as well as family.

To conclude, living long has its own advantages and disadvantages on both individual and a society.
