Fear of roller coaster can your fear change overtime?

I spent my weekends all throughout high school going to 6 flags with my friends I lived near one so that was kind of the hang out spot for teens in my area. I road every roller coaster a million times and had no fear of roller coasters, I always felt I would need to go skydiving to get a adrenaline rush. Now I am in my late 20s and I have developed a fear of roller coasters. I talked to my sister in law and she said same with her as she got older she then became afraid but wasn’t in her teens early 20s. She felt like she actually developed a fear after having children. I have no children but still feel something changed in me to develop fear that I didn’t have before. Do you think it’s possible as we get older something can change to make us more aware or fearful of these kind of intense rides?
