The Wall Street icon spent six months fighting throat cancer last year (10), undergoing chemotherapy and radiotherapy treatment.
He was given the all-clear earlier this year (11) but is continuing to undergo regular check-ups to ensure the tumour doesn’t return.
Keen golfer Douglas has signed up to be the star guest at this week’s Alfred Dunhill Links Championship at St. Andrews in Scotland, and he is hoping the challenge helps him relax.
He says, “It has been a few years since I played. I love the place and the atmosphere and I have missed it a lot.
”It has been an eventful time for me recently. However, I am now feeling good and am looking forward to an excellent week on some of the greatest links courses in the world.”
