I would invent a high def, high res camera that could b implanted without changing the appearance of ur eyes. And it would work off of electrical impulses from ur nervous system when ever you want to decide to record or snap a picture. It would download and save to a device tht you could connect to a computer or laptop and be able to replay back. Imagine, reliving the first time u went cliff diving, or snorkeling, or that amazing sunset after that long hike. Or ur child's first steps. Haven't u ever lived a moment that u knew u would remember but wished u could keep forever somehow? I've had plenty. I think moments and memories are all we really have in the end. So it would b important to me to save the best ones to remind myself what a crazy and full life I lived.
