As a writer, you should always try new things. They say write what you know. By exploring new things in life, you're expanding what you can write about. A lot of reading helps that too lol.
Look into yourself and discover what you've always wanted to try but never thought you could. Sky diving, bungee jumping, etc. You can write about your adventure in learning or trying it for the first time, the fears that came with it. Or you can use it in a book as something the character did. Either way, you've expanded your horizons which is a very good thing.
If you can't go to the place where you have to learn it, talk to people who have done it, read the books. There's plenty of ways to learn those things.
And have fun doing it too!
