95% would use it. Why so many? Because most will live to old age, sure, but as soon as they fall apart and the death process starts, they will want to end it just like us younger suicidal people here, because at that point even the most pro-life person will know that hope is now useless and death is imminently unavoidable anyway. The medical practice already helps people ease into death with medication. The rest 5% (not exact figure) will have died by accidents before they can make a choice.
