Can you learn an axel after the age of 40?

Are there any adult ice skaters out there. I've been trying to do an axel for years now. I can do one on the ground in my gym shoes, but not on the ice. Am I too old to do one now? Should I give up or keep trying? What age is too old to learn an axel? Once I put my skates on , they just weigh my body down and I feel it is too hard to jump high enough to do it. Or maybe I just chicken out from fear of falling or spinning out of control.
