A nice gift for my father

When I was searching a gift for my father on this coming father's day,I saw these medical id jewelries such as medical id bracelets.I think my friend gave the same thing to her mother in law.Since she has some issues on her medical condition and taking some medicines,so whenever she goes out,she never fails to wear it.It is very useful incase of emergency because all of the important informations on her medical condition and medicines are engraved to her id bracelet.I think it would be a nice gift for my father.
