That's a very good thing done. I used to have one too. Actually, it was my parents'. But I used it for running when it was raining hard outside and I didn't want to get soaked. Now I don't care, I don't mind getting wet, it proves I'm alive and well.

That said, there's something nice about having a mat to walk or run on: you can watch your TV series at the same time haha. Some might think that's sad, but I think it's really cool!
