A ring or bracelet can be given more lasting value by the memories associated with it. That’s why, I suppose, people care so much about the inheritance of family jewellery and why eg watch manufacturers centre their advertising on the idea of passing their (pricey) products on.
Today’s invention is a ring which can add sentimental value to itself.
The ring would have within it a heart rate monitor. This would record the times when the wearer’s heartbeat exceeded a certain level. The ring could then be wired up to eg a mobile phone (without being removed) and request verbal annotation by the wearer of the exciting events of the last day (or week).
Over time, this would build into a personal history of successive generations of wearers.
