Former MLB star Alex Rodriguez, who now runs an investment company, A-Rod Corp, and commentates for ESPN, works 80 to 100 hours a week. And he relies on a lot of caffeine to get through each day.

His schedule is "filled with meetings and phone calls and lectures and TV appearances, with his weekends fully accounted for by his ESPN duties," Ben Reiter reports in his Sport Illustrated cover story on the reinvention of A-Rod, who was suspended for the entire 2014 season for using performance-enhancing drugs.
