I’m 40 - too old for staying in hostels?

I’m going to spend 2 months traveling around Thailand. I’ll be traveling alone and would enjoy to meet different people along the way. It’s been quite a few years since I last stayed in hostels but have a slight craving for adventure and excitement again since splitting up with my ex.

I’m by no means a party animal at all - but happy to spend half my nights in hostels and meet people.

Am I too old for that??😅
