Elderly Americans experience about 29 million falls per year, which costs Medicare $31 billion. At about $1,000 per fall that seems quite reasonable. 27,000 older Americans die from falls each year. In an institutional setting like a nursing home, the rate of death per fall is even higher.
$700,000 for two people in assisted living for eight years is about $43,000 per year. That's not unreasonable for the cost of assisted care plus medical expenses.
