Do you think the voting age of 18 is appropriate if you were to change it would you make it higher or lower in my

I believe the voting age of 18 is appropriate.

Explanation:

At age 18, an individual is an adult, and often has all the responsibilities of an adult. Policies on issues such as taxation, healthcare, and other important topics can and will directly affect the lives of adults, and voting on such issue is another one of the responsibilities adults hold. Allowing children, who are often unable to take care of themselves, to assume the responsibilities of making informed political decisions, while bearing little to no responsibility for the effects of such decisions would certainly be folly.
