I wish I was also a retired guy who can just travel and don’t worry about anything

) my biggest suggestion is to visit Greece – the weather is nice, the sea is warm, and the beaches are big.
If you are a fan of excursions and history, there is a lot to see there too for obvious reasons. You can also travel to other European countries from Greece. In Germany, as I’ve heard,
the railway tracks are very good, and you can go to almost any point in the country just by train. This summer there also is very cheap 9€ tickets that can get you to so many touristic places.
