I'm as young as I feel...don't ask. But I have to stay current for my ever younger client base...which, surprisingly, isn't that difficult to do. In any case, this old XP machine has provided many, many years of solid service and is ready to be retired.
As to staying current...I will never stop experimenting, exploring and learning from those younger than me and more in tune with new methods and processes.
(Even if they are bewilderingly dimwitted) ;-)
