Travel broadens the mind but there are limits - with some countries best avoided.
The UK Foreign Office advises against travel to at least parts of 73 different countries and territories at the moment - a figure which has increased in recent years.
When it comes to judging what countries are the most dangerous, the international health insurance experts at William Russell have looked at the 2024 Global Peace Index and the latest World Risk Report.
These assess factors like crime rates, political stability, terrorism risks, and natural disaster resilience.
They have also consider healthcare access and quality, as well as digital security, which is increasingly important in a world where cyber threats are on the rise, to come up with a definitive ranking for 2025.
Here are the 10 most dangerous countries on the planet.
