Worlds oldest teenager right here. Still have a lot of energy but just not enough time with my own career, children in sports, high tuition schools and house repairs and spending time on here. LOL.
Complicated car I have and it goes into maintenance and or modifications at a slow pace to stay fast.
Sometimes all I have is an hour and by the time I get to the grotto to twist a wrench, it's time to go.

Time is a luxury more than anything else.
