If it comes to having children, would you prefer to adopt or to be one of the biological parents?

I dont want kids , however , if I ever change my mind , I rather adopt. I have really bad food allergies and have an chronic ilness , I wouldnt want to burden an child with that just in case it could be gentic. Theres too many children in this world who are waiting for forever homes but never do get adopted. If I find it isnt gentic then maybe I would consider both but I cant really say right now. Child birth does freak me out because it can cause complications and pain , I dont really know if I could risk that.
