Elderly falls are responsible for 27000 totally avoidable deaths and $75B annual costs in US alone. One in three people over 65 experience a fall every year and technology can be used to avoid all of that!
It’s not one of the biggest of the problems like people dying in road accidents (37000 deaths + 230B annual cost) and technology coming up with self driving cars but it certainly is a good size problem. Let’s say you save 1% from the cost of falls, that’s $750m and that’s US alone!
An elegant and effective solution will take years, the market is locked and very hostile, however, what about starting from the prospect of saving 270 lives a year? At best, this frontier market will be saturated in next 5-10 years.
