Answer:
The voting age of 18 is appropriate.
Step-by-step explanation:
The age for the voting age has been argued many times, but essentially the argument boiled down to 18 being the appropriate number because 18 has been put as the "adult" age, as it is the age in which one is able to join the armed forces (either voluntarily, or, during times of war, conscripted). The argument made is that if 18 year olds are sent off to die for the country, then they should have the choice of being able to make political statements through voting. The voting age should definitely not be lowered, as the brain scientifically does not fully mature until ~25 years old.
