What would be the purpose of a friend calling you up and telling you, in relation to your health, "enjoy your ____ now because when you get older, you're going to have problems with it?"?

Last weekend, I slept with my contact lenses on, due to forgetting to bring lens case out. The next morning, my eyes were very dry and painful.

A friend of mine, a hypochondriac (I’ve discussed her here a few times recently), after hearing my tale, called me up out of the blue and said “You know, I was thinking about how you said your eyes hurt after sleeping with your lenses on. I was thinking that a most older women can no longer wear contact lenses due to their eyes becoming dry. So enjoy your contact lenses now, because in the future, you may not be able to wear them.”

I pm’d her on FB, after thinking about her statement, and told her I felt like that was not a helpful thing to say. I told her I feel like there’s no purpose in becoming anxious about things that may never happen and that can’t be controlled.

What would be the purpose of someone saying something like what she said? I can’t figure out what the reasoning would be, other than to try to instill anxiety in someone (which, by the way I’m a pretty unanxious person).
