Is 27 too old to start travelling?

I had the money back at uni and i never took the opportunity because i was just so nervous. I wasted my student loan and regret it so much. I am only currently learning to drive also. But i want to save and travel before I get old. I would be going solo as my friends and I have just drifted apart. I'm scared it's all going to be young 18 year olds and I will be seen as over the hill and won't fit in. Places I am looking at is Budapest, Thailand, Asia, Germany, Sweden
