And going on a tangent using Google to find ages for cartoon characters all come from clickbait backwater sites with no sources and those dumb character, hero, and villain wikis with no sources. I dislike how searching things on Google leads to a lot of misinformation, because they scrape their information from fake and terrible websites.
Super Princess Peach release on the DS in 2005 the game is 16 years old. Mario Bros was released in the Arcades in 1983 the game is 38 years old. That is the info that the google searches in OP's tweet is conveying. Not the actual ages of the characters themselves. Thank you for coming to my Ted Talk
