I really don't know what the life expectancy is but my mothers aunt had it also and she lived a full life I believe she was in her 70's when she passed. Allergies is and can be life threatening so know what temperatures you can handle and be aware of your surroundings weather it be wind, snow, rain or air conditioned areas, your knowledge of what you can handle may just save your life also it will help with a long healthy life.
