Show HN: What's your mental age? Try It

https://mental-age-test.app
2•takennap•47m ago
I’ve just updated the design of to make it cleaner, faster, and easier to use on both desktop and mobile.

It’s a short “mental age” quiz you can finish in a couple of minutes. No login, no email, just answer the questions and see your result.

I’d love feedback from the HN community on the new look & feel, usability, and any rough edges you notice (copy, UX, performance, etc.). Thanks for trying it out!

Thanks for this

If your formula is “actual age minus twenty”

I’d say your mental age (and sense of humor) are in a very good place.
