After my dad retired, he got hooked on stock trading, and every day he tells me, “I made money again today.” I ask how much he earned, and he says, “Two hundred.” I tell him, “That’s not much.” He says, “It’s better than working. You only earn five hundred a day at work— and it’s not that tiring.” I say, “Is there something wrong with your math?” He says, “You don’t understand. The two hundred you make from stock trading is basically free money, but the five hundred from work is risking your life. Free money is better than risking your life.”
