Do you remember family phone numbers lately ?

I bet 90% of people in world do not remember mobile / phone numbers of their home, family or friends, recently i forgot my cell phone and i was too far away from home and urgently required a mobile number of my friend but unfortunately i was not able to remember numbers of my mother and sister nor anyone @home, and one thought that came to my mind is who should i call in an emergency? because i haven't memorized any number? though i remember landlines number it is in my room and only used for internet/broadband and this shows how much we are dependent on stored numbers in our mobile phones and handheld electronic devices.

So how to remember phone number in case of emergencies? below are few methods that may save you in case of emergencies:

1. First of all try to memorize two phone numbers one is your family member and other is your best friend.

2. It would be a better practice to maintain a "phonebook /telephone index" for important contacts and emergency numbers, i guess this was the common mode of storing phone numbers before cell/mobile phone became widely used.

3. Sync contacts to web via mobile or store contacts into web such as yahoo, google or hotmail so that you can access contacts via net in case of stolen mobile or if device is not handy we can just browse online contacts to get numbers anywhere anytime provided we have access to internet.
