18... drs a difficulty choosing a career at the age of 16... who wants the 16 year olds to vote on influence by family members , friends, nieghbour hood or anyone or simply make a waste of their votes? It can also result in a misbehaviour for every child leading him to not vote later on when his vote is important or also there can be various other issues with such teenagers...!! I believe that the age ideally should be 21, as the person at this age generally aquires good political knowledge and also a decision making power to select the right candidate...
Voting in our country is jus another holiday or a joke or a means to earn for certain... voting with a thought of a beautiful country can change the lives of millions.
Think simple and rationale... just dont create doubts for the sake of it!
