Can an older person learn new mechanical principles?

How did you find PF?

Google search

I'm just trying to better myself and looking for help with a couple of questions on mechanical principles. I need any answers in laymans terms please as I'm not exactly a spring chicken and have not studied anything like this in several decades
I'm hoping some of you young guns (and old wise persons) can help me out.
Cheers,
