According to science, the adolescent brain is not fully formed until age 24. At 26, most students have not been able to understand what they need to know to make good decisions about life. I have taught high school fo over 18 years. There are some responsible ones, but most are still immature. Keeping the voting age at 18 is much more responsible. I also believe that the driving age should be 18. The accident rate with younger drivers is still very high.
