Treadmills.&.Dumbbells

Yup! I'm going back to the gym again. Had an invitation from my colleague and I spontaneously agreed to sign-up. Guessed I have to get back in shape since stopping in 2002. Need to make myself feel healthy again and regain my stamina so that I can climb flights of stairs (never know when is the next fire-drill) and won't fall asleep easily when reading technical articles *HeHe*.
