Carol Vorderman made a plea to her followers encouraging them to get involved in blood donation.
The former Countdown star posted to Instagram, showing a video of her having her blood taken, with a large needle in her arm. Despite being sat in a hospital-looking setting the 62-year-old TV personality sat grinning as she carried out her good deed.
She captioned the clip as she said: "I became a blood donor this morning @givebloodnhs at our local hospital Southmead Hospital, Bristol. It was honestly so easy."
