31 here. Growing old for me was mostly about accomplishment, "am I doing everything I want/need to do while I'm still young?" I mostly am succeeding, have a nice stable career and am a father of one. I admit that this success was mostly dumb luck and I didn't have any master plan or list of goals. You're where I was when I was your age, you might benefit from introspection to see what you want to get done before you hit age milestones, and go and do it! As for the "everything new is dumb bit," yeah that happens to most people. I encourage you to force yourself to listen to new music and experience current culture. It's very easy to become ossified over time, and you should grow older with an open mind about all things. By the way, I've found that making memories and experiencing new things with friends and loved ones is the best way to not only slow the passage of time, but also pacify the thoughts of "oh god I'm getting old." Having a pool of memories to attach to your age helps your thoughts go from "I am afraid of getting older" to "I can't wait to see what else I get to do."
