A young woman who was a graduate student at my school lost her life to an attacker while she was jogging recently. It was during the day and she was jogging alone. She had her phone with her. The university community will mourn this loss, but if anything let us learn from it.
There are many disturbed people out there. Please Please Please be careful.
A few tips for personal safety:
Walk or jog with a friend.
Avoid jogging after dark. If you must, stay in well-lit areas
Walk midpoint between curbs and buildings and away from alleys and bushes.
Tell someone where are you going and when you will return.
Much love and care.
