Studies with promising early results like these, such as the tooth-regeneration study that is expected to complete its Phase I trial soon, really give me hope for being able to grow old while staying healthy.

It does make me wonder how long it'll take until we've reached the end of things to cure, and what might come after.

10 - 15 years from now I won't be surprised if artifical eyes with IP(or some sort of digital connectivity) with either self-charging via solar or heat from our bodies will be a product.

A bigger problem for old age is cataracts. In that case you need an entirely new lens anyway. By age 75 at least 50% of people are developing cataracts.
