It is the time for me to exchange the cell phone old and infrequently used.

 My cell phone is pretty old. Maybe, around 15 years of usage. 

When, working at own practice, I sometimes had patients who should be monitored throughout the night. In such a case, I gave them and their family members my phone number and told them to give me a call when they got worse. I have had an emergency call once or twice in a month. But, seemingly, they were relieved to be able to get in touch with me, even though I had to tell them I should switch off the cell phone at midnight. 

My old cell phone has a large data of those patients' phone numbers. When I quit working at own practice, I wondered what to do with it. I thought some patients or their family members might had consulted to me on the phone when they had any health issue. Actually, it turned out nothing. I understood the patients won't rely on me when they lose relationship with me as a doctor in charge or they have found certain new doctor in charge. On the other hand, I often recall some of them even in dream. The other day, I realized they had become grown up and even became parents themselves for now. 

So I believe it is the time for me to get away from the sentimentalism of being a doctor in charge of those people. I still have good memories of them. When I thought to be a doctor, I was thinking of becoming a school teacher. In that case, at their alumni reunion, I could have seen the pupils or the students whom I was the class room teacher for. How nice it could be if I could see the patients grown up and living at various positions in the society. 

Unfortunately, I am not able to see them any longer. Just wishing them happiness and good health.

Quiting such a daydream, I should change this old cell phone to a new one or to a smartphone. It is the time for me to go ahead. Can I manage a new phone by myself?
