Well, of course, I agree with you. But he has rejected my proposal. He seems to think that the future will be like the past.
He does not factor in that he is getting older and that other changes are going on. ATT wants to get out of the landline business. It is likely that he will have more and more "disruptions" to his landline service since ATT will not spend the money to keep the lines in good repair. The safety-while-running issue comes on top of all this.
He obviously feels safe running at 2 am if not he wouldn't be doing so. It is far safer for a man to run alone compared to a woman. In the event of a woman being attacked, I don't actually think that it helps having a phone. Look at all the recent stories about woman joggers who have been murdered.
He certainly risks being bitten by a dog or falling over more than being attacked. However, he seems quite confident and has no desire to have a cell phone.
I don't quite understand his remark about 'the future will be like the past' !!!
