Can you be too old for anime?

So I am a big fan of anime. So recently a question pop in my head. . . . Can you still be in the age 50s and still enjoy anime? So I look it up and I saw some people who said they are in 40s and still watch anime. I am just scared that I am going to grow out of loving anime and yaoi. So I thought I like to hear other opinions on this. By the way I am still a super young teenager( best not to state my age lol) and in high school.
