I want to know the answer to the following question:
Over how many years did Bell spend a great deal of time at Beinn Bhreagh?
All the background I'm provided with is that "Dr. Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake.". Is that enough to answer the question?
Answer: yes
