even if you have no symptoms now, it's not impossible that they'll still pop up later in life, even after all this time.
I'm far from the person you should take advice from on this, but no one else replied. it doesn't sound like signing up for this without any active condition will add much burden. it sounds like, if you're taking clear, the only thing you'd get out of this is a screening for relevant health conditions, and the option to recurve specific care related to this later.
