Over here in Malaysia, people who are in need are not in the habit of using medical jewelry, which leaves much to be desired.
Recently, a colleague and her family went through a harrowing experience as her sister suddenly collapsed while out shopping and ended up in a hospital.
Paramedics who came to her rescue had no idea of her medical condition. Her sister is diabetic. If she had a medical id with her, treatment would have been more precise and speedy. Luckily, her sister survived the ordeal. After that incident, the family insisted that she wears a medical id. She was given the choice of a watch or a bracelet. She picked the bracelet. Medical ids could save lives so wear one if you need to.
