Me & Brad Pitt

Brad Pitt recently commented on his age and living his 50's over again. The difference between Brad's birthday and mine is as follow; BP was born December 18, 1963 and PG born February 11, 1972. This is 8 years, 1 month, and 24 days (or 8.15 years if expressed as a decimal) differrence. The breakdown of the duration; Total Years: 8 years (Dec 18, 1963 to Dec 18, 1971). In total, this equals 2,977 days between the two dates. I wonder what Brad would give to have 8 years back?
