Why jog on the highway?

I find it difficult to understand why there are people who enjoy jogging along highways and willingly expose themselves to the risk of getting hit by one of the fast moving cars, especially between Muara and Kuala Belait.

Recently I saw a lone girl jogging towards Tutong District at 6.15am, and thinking to myself: “How dangerous is this, especially with poor visibility this early in the morning?”

While I understand the importance of exercising, there must surely be an alternative to jogging metres away from moving cars.
