No, but the older you are, the harder it is to learn to speak a foreign language to a near-fluent standard, although going to live in a country in which it is spoken can make a huge difference.
I'm 62 and about to study Ancient Greek, something I always promised myself I'd do later in my life. I have a lot of language-learning experience, though if I actually had to learn to speak Ancient Greek, I doubt I'd do very well with it, at my age.
But studying a new language is always a great idea. Bonne chance!
