My mother works full-time at age 70, my father (71) is disabled and has been disabled for 30+ years. She works as a cashier at a drug store where the prescription costs are reasonable. She states that she needs to continue working because of the insurance benefits and prescription benefits. My father has many health issues and requires multiple doctor visits, she pays out of pocket to have a handy-ride type transportion. I worry because she has had major back surgeries and had a stroke last year requiring a carotid endarterectomy. She does all of her own shopping, cooking and cleaning as my father is unable to help due to his health issues. She has worked all of her life. She says that she cannot collect Medicare or Social Security benefits (?) because she is working full-time. She enjoys working but would like to work part-time but cannot afford to.
