Medishield life extra premium for schizophrenia patients

I am little puzzled by the medishield life definition of schizophrenia as a serious medical conditions which require extra 30% premium because i just went for my med review at saf today and they said i still can serve the country meaningfully despite being diagnosed with schizo, a condition deem serious to warrant 30% extra premium.

I am really puzzled and hope to get an answer from our esteemed ministry of health and ministry of defence.

Thank you.
