One thought about traveling in your 20s vs later in life - regardless of whether you feel it will be BETTER or WORSE for you, it will likely be DIFFERENT.
I spent a year working and backpacking in Europe when I was 19. I was single, outgoing, spontaneous, had never lived away from home, in perfect health and had extremely low standards for personal comfort. Everything seemed AMAZING and often completely novel - I was seeing things for the first time rather than seeing an 'up close' version of cities and cultures I was already familiar with from the internet, television, and years of experience with their expat populations in Melbourne.
Only 14 years later and I would experience the same countries in a very different way. I can drive now, I need more sleep, I have a more nuanced understanding of history and culture, I like wine, I'm more risk averse, I have a greater appreciation for nature vs big cities, I am more reserved with strangers.
If indeed there are benefits to travel such as perspective, empathy, cultural awareness, and perhaps for someone like my 19 year old self, building independence and self reliance, I got to enjoy them for the next few decades rather than waiting until my 50s. Of course, perhaps I could have built my independence equally as well back at home. I'll never know.
All I'm saying is, don't expect to have or want the same experience in your 50s that you'd have in your 20s.
