I have been going to the beach and exerting my arm muscles at the out door gym over there. --though it occurs to me to wonder "Why I bother? After all it is not as if I am lifting weights," Then today I heard some mother yelling at someone in the water that I could barely see. Somehow it sounded different than other people screaming for fun at the beach.  It occurred to me that that fellow in the water might be in trouble. I ran over and the mother called to me in English "It's my son! It's my son!" I got the idea that he needed help. So I ran out there battling the waves until in fact I got to an area where there was no ground anymore. I needed to swim. I finally got to that guy and yelled at him, "Give me your arm" [in Hebrew תן לי את היד!] and grabbed his arm and dragged him back to shore. But I was barely managing on my own. After all I have not been keeping  my muscle strength up. At any rate, I realize now why it is important to keep up one's muscle strength in one's arms===to be prepared for the day that someone might need your help.
