What’s backpacking for an extended period of time like in 30s

Hey guys. I’m 34 and I’m thinking to go and travel carefree for at least 6 months at some point next year. I’ve moved around a lot in my 20s for uni and work but haven’t experienced true backpacking adventures. I always kept putting it off because of financial obligations, career and obviously covid. Has anyone travelled extensively in their 30s? If so what can I expect? Am I too old to stay in hostels? Do I meet people and make friends easily? Would it be as fun as if you’d done it in your 20s or have I missed the boat?
