Oh my, we have to be flexible with technology, especially older people, even if it´s just learning the basic functions of a mobile phone. I once got so dizzy at home after coming back from walking the dog of my girlfriend (She was in the hospital for a check-up), and when I was going to give him water, I collapsed, fell on the floor, and sprained my ankle; the water splattered all over my face; I had a heat stroke. Thank God, I had the phone with me, so I was able to call an emergency doctor, and an ambulance came after about 8 minutes.
