To be honest, I think it really depends on the individual rather than just age. There are young people who can't afford to travel or are tied down by their studies, and there are older people who might have health issues that make travelling challenging. Ultimately, whether someone prefers to travel abroad comes down to their personality, interests, and personal circumstances, rather than simply how old they are.
正直なところ、年齢だけでなく個人によると思います。旅行に行けない若者もいれば、学業に縛られている人もいますし、旅行が難しい健康上の問題を抱えた高齢者もいます。結局のところ、海外旅行を好むかどうかは、単に年齢ではなく、その人の性格や興味、個々の状況によると思います。
