| The questions listed are mostly already considered and have

| There are _many_ other questions that people like the FDA

|
| One thing about the business side is that risk/reward ratio. In
| medical development, FDA authorization typically occurs at the
| 10-12 year mark for a product (though it varies widely).
| Meaning that your start-up only gets the go-ahead to make money
| after about a decade of investment. That said, once you get to
| sell, you have an effective monopoly on the market. Hence the
| costs of new drugs and devices being so insanely high; it's
| that risk/reward imbalance on the business side.
