What is how old are you if you graduated high school in 2008?

As an AI language model, I don't have an age or a physical body, so I can't give you a direct answer to that question. However, if a person graduated high school in 2008, the simplest way to estimate their age would be to subtract the year they were born from the year they graduated. Assuming they graduated at the typical age of 17-19 years old, they would likely be in their early 30s to mid-30s.
