It is said that night jogging has become a fad in some area.

Most joggers are young men.Because at daytime they have to sit in the office,and have little tme to do exercise.

Some even set up a Internet chat grour invite the people who want to jog.And the air at night is cleaner and the temperture is lower.

Also there is one single jogger who shares the same passion with the group.

For myself, i prefer to jog in the morning.And i deside to jog from tomorrow.
