That depends on the person though doesn't it? I'm not sure what I'd do in that situation. But 7% seems awfully bad odds for painful and debilitating life.
I guess that depends on the exact scenario. There are likely people with a variety of conditions who enjoy their lives vs having not been born. It brings up a seemly logical contradiction that we terminate fetuses (potentially viable in some cases) on the assumption that they don't want that life yet we don't allow people who want to kill themselves to do so.
