Lewis Hamilton says he is "loving" his world championship battle with Sebastian Vettel so much that he has banished any thoughts of retirement as he heads into Sunday's last-ever Malaysian Grand Prix.
At Sepang a year ago Hamilton thought the world was against him, spouting conspiracy theories when his Mercedes engine exploded while leading, which handed a 23-point championship cushion to team-mate and eventual champion Nico Rosberg.
It left the three-time world champion at such a low ebb that there were rumours he could retire.
"I definitely have thought about (retirement)," the Mercedes driver admitted on a British TV chat show at the weekend.
"But then we're in the heat of this battle right now and I'm loving it more than ever. It's the greatest feeling ever so I'm going to keep going for as long as I can and see what I can do."
