We shouldn't encourage people who can't properly read and understand a comment before replying either, but here we are talking to you who jumped on correcting the “2 or 3 years” to “19 years” without noticing that “2007” was in the post so the poster was obviously well aware of that.

1. That is not the joke. It is referencing how humans experience the passage of time at massively different rates to the actual reality, especially as we age.
2. Humour is subjective. So is, to an extent, the amount of it that is acceptable in a given environment. Sense of humour is sometimes objectively non-existent, as you helpfully illustrate by clear example.
>“2007” was in the post so the poster was obviously well aware of that.
Which is why I first included the possibility the commenter didn't know the current year.
>humans experience the passage of time at massively different rates
The commenter did not say anything related to this. The relative speed of time was not referenced.
>that is acceptable in a given environment
Humor is not very acceptable on this website compared to others, so it's important to protect this and not let outsiders from other sites to try and bring their humor here.
