By that time, he had completed 22,220 solo engagements since 1952. He had also given 5,496 speeches in more than 76 countries, authored 14 books, served as patron to 785 organizations, and made 637 solo overseas visits. All while being married to Elizabeth since 1947.\r\n\r\nPhilip often times likes to spend time at Wood Farm on the Queen\u2019s Sandringham estate in Norfolk. He moved to Wood Farm after retiring in 2017. While there, he enjoys quiet pastimes such as reading or painting watercolors. This means he often is away from Elizabeth, but due to the lockdown measures, he has been quarantining with the Queen for a while now.\r\n\r\n\r\n\r\nBack in December 2019, Philip was hospitalized for "observation and treatment in relation to a pre-existing condition." He was subsequently released from the hospital on Christmas Eve. We hope that Philip is in both good health and good spirits for his 99th birthday! What an incredible milestone. Happy birthday to Prince Philip!
