Voting age should be raised to 21

• 18 is too easily swayed by immoral politicians
• the judgmental area of the human brain isn't fully developed until the age of 19 . With age comes sagacity and deeper understanding without the kneejerk, emotive reactions experienced by the youth
• One needs to have some experience of the world . 21 would be the minimum age
• Politics at school/college may be tainted by teachers' bias and so can't be deemed independent. By 21, everyone should be able to use their own experience to decide
• Extending the period where the person is unable to vote may increase their desire to eventually vote when they hit 21 . 21's have experience from work , training or university
