* Life Magazine ceased publication in 2000. While there were some special editions after that, it's not a current publication.
* Sports Illustrated has a long history, but it's primarily focused on sports. It's unlikely someone would be on the cover of both magazines unless they were a very famous athlete.
Therefore, it's difficult to find 5 people who have been on the cover of *both* magazines.
However, I can provide you with 5 people who have been on the cover of Sports Illustrated and are also likely to have been featured in Life Magazine during its active years, given their fame and impact:
1. Muhammad Ali: One of the greatest boxers of all time, Ali appeared on many Sports Illustrated covers and was a major figure in popular culture, making it very likely he was also featured in Life Magazine.
2. Michael Jordan: Another iconic athlete, Jordan was featured on numerous Sports Illustrated covers and dominated the basketball scene in the 90s, a period when Life was still active.
3. Tiger Woods: One of the most successful golfers of all time, Woods was on many Sports Illustrated covers and was a prominent figure in the public eye during Life Magazine's later years.
4. Serena Williams: A dominant tennis player, Williams has appeared on multiple Sports Illustrated covers and is a global icon, making her a likely candidate for a Life Magazine feature.
5. Jackie Robinson: A trailblazing baseball player who broke the color barrier in Major League Baseball, Robinson was featured on the cover of Sports Illustrated and would have been a subject of interest for Life Magazine.
Please note that this is just a possibility based on their fame and the timing of their careers. I can't confirm if they were *actually* on the cover of both magazines without further research.
