Possibly, if anything, being older might help you when learning Blender. Even if it might not seem relevant on the surface I bet you’ve established many life skills and points of reference that would apply, if not to Blender directly, to the process of learning itself.
I’m 55 – admittedly I started learning 3D in the 90s but it was very (VERY) on-and-off. It’s only been relatively recently that I’ve moved out of my comfort zone (sculpting) and started expanding my knowledge of Blender. I definitely don’t believe age is an issue at all – if you apply yourself with patience and confidence then that’s the most important thing.
