What is the solution for ivdp for old age?

Prevention is best: By 'ivdp' I assume you mean intervertebral disc prolapse, or a slipped vertebral disc. Are you talking about prevention, or to treating existing pain, even disability. Prevention includes plenty water, healthy diet, regular exercise, & (esp. RE lumbar) avoiding prolonged sitting. Treating symptoms, depending on severity, may well require visit to clinician or physical therapist. Hope that helps.
