What sparked your interest in science at 67 years old?

[Ken Lehn]

Hello all,
I'm 67 yrs old, retired machinist, raising 3 young grandkids. I've always had an interest in all things science related. My formal education ended almost 50 yrs ago with undergrad chem, math, physics courses. Still curious though...
