When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
A study of Shell Oil employees shows that people who retire at age 55 and live to be at least 65 die sooner than people who retire at 65. After age 65, the early retirees have a 37% higher risk of death than counterparts that retired at 65. That's not all.
