Good news! Today you can identify as any age you choose. Make believe is reality, so if you say you're 23, you are. Period. You could even identify as an under-dash creeper.....which might have a couple different meanings here, esp if you start hitting on actual 23-year-olds......Replaced the Hydroboost on my 2002 GMC 3500. Laying on my back under the dash with my legs hanging out of the truck was a lot easier at 23 than 63.
