The former MP and close confidant of the Queen came to this realization after chatting with actor Rupert Everett about his own vivid escapades.
Through his conversation with the British star, Brandreth acknowledged that his own life seemed mundane and uneventful in comparison.
At the age of 76, Brandreth disclosed that he has abstained from drugs, smoking, and excessive drinking, which in turn led him to feel that he has not truly experienced life to the fullest extent.
During his podcast interview with Everett, Brandreth discovered the actor's colorful and adventurous past filled with wild encounters.
He remarked on Everett's uninhibited approach to relationships and his unapologetic attitude towards discussing his past experiences.
Reflecting on his own life choices, Brandreth noted that he has lived a more conservative and restrained existence in contrast to Everett's bold and indulgent lifestyle.
Despite Brandreth's commitment to a healthier lifestyle which includes eschewing alcohol, drugs, and cigarettes, he pondered on what could have been if he had taken more risks and embraced a more adventurous approach to life.
On the other hand, Rupert Everett, known for his acclaimed performances in films like "My Best Friend’s Wedding" and "The Happy Prince," has been more open about his relationships, experiences with drugs, and the need to give up certain substances to focus on his career.
In terms of personal life, Brandreth has been happily married for many years, leading a contented life with his wife Michèle and their three children in London.
Apart from his decision to avoid vices, Brandreth has also adopted a vegetarian lifestyle, prioritizing his health and well-being.
Overall, while Brandreth may feel he has missed out on the thrilling experiences that others like Everett have had, he remains content with the life he has chosen, filled with routines, healthy habits, and a loving family.
