Was at gym earlier, started with a 2.4km jog follow by the various weights machines. It was around 40 minutes after I started when I suddenly realize I didn't remove my key from my locker after I have changed into my gym attire. I immediately dash to the locker room and phew, the key was still there hanging on the locker door. Opened the door and everything was still intact.

I'm like so careless recently. It's the first time this happen during gymming. I'll ensure no more same mistake in the future. I'm glad I have been lucky enough not to lose anything. My hp, my keys, my wallet.... Phew!!
