OMAHA, Neb. (AP) — Warren Buffett will turn 85 on Sunday, but he’s shown no signs of slowing down or retiring from the Berkshire Hathaway conglomerate he built over five decades.

Buffett has long said he enjoys running Berkshire far too much to consider retiring.

This year, Buffett’s friends and family may have an especially hard time shopping for the billionaire because earlier this month he just announced the biggest deal of his career.

Berkshire agreed to buy Precision Castparts for $32 billion, so if regulators and shareholders approve, the aerospace and industrial company will soon join Buffett’s firm.

Of course, Buffett is known for his relatively simple tastes for cheeseburgers, steaks and Cherry Coke. And he continues living in the Omaha home he bought in 1958.
