A 104-year-old has been a professional lobster woman since she was 8. She says the secret to her longevity is keeping busy.

• Lobsterwoman Virginia Oliver, 104, has worked in the family business since age 8.
• The centenarian gets up at 3 a.m. thrice a week to start her shift on the water in Maine.
• She told Business Insider she will stay in the job "until I die."

She might be 104, but Virginia Oliver won't quit lobster catching — a job she's done on and off since she was 8.

Thick fog, stormy seas, and heavy traps haven't stopped the centenarian from stepping aboard her son, Max's boat, three times a week.
