Here are the top three questions asked of American lecturer Richard Rodriguez on completing his world record-breaking 1,000hour marathon on the Big Dipper roller-coaster in Blackpool.
Did you pay for each ride? Nope. How did you go to the toilet? On my breaks. And thirdly, er, why on earth did you do it?
To answer the Why you have to go back to the Coney Island fairground in New York, where Brooklyn-born Rodriguez (39) saw his first roller-coaster, The Cyclone.
"I was scared of them as a boy to be honest, but I grew to be fascinated. When I heard there was a world roller-coaster record I decided I wanted to do it. My first one was 45 hours and I did it just before I graduated," he says.
In Dublin to promote the new Imax movie Thrill Ride - The Science of Fun, he says he has sore bones and joints but no other ill effects.
His face is bright but weatherbeaten. He looks and sounds perfectly sane.
The 47 days he spent on the classic, if slightly rickety, Big Dipper were he says, "the equivalent to driving from Miami where I live to Anchorage, Alaska with no windscreen on your car."
The Coaster King had gone into retirement after beating the world record of 549 hours in 1994, also on the Big Dipper at Blackpool Pleasure Beach. But when he heard that arch-rival Normand St Pierre was attempting a challenge in Montreal, it was enough to tempt him back to Blackpool.
Poor old Normand gave up after 670 hours, at which point Richard decided to go for the 1,000 target. "Some people were a bit concerned but Geoffrey Thompson, the MD of Blackpool Pleasure Beach, is really gung-ho about the record and he was all for it," he says.
Under the Guinness Book of Record rules, he was allowed take five minutes for each hour on the roller-coaster, which he saved up for a one-hour break each morning and evening.
This time out was used for eating, drinking and bathroom breaks. A diabetic, his insulin was sometimes administered while in motion on the bone-jarring Big Dipper. The challenge has raised thousands of pounds for diabetes charities.
What really kept him going, he says, were the holiday-makers who came to visit him in the red and yellow car that was his home for 47 days.
"People from all over the world came to chat with me and give me support," he says. "I met a little boy and girl, now grown up, who had come to see me on a similar challenge in 1979."
At night, as the wind howled and the rain poured over the Blackpool Pleasure Beach, blankets and tarpaulins covered him as he slept in the foetal position.
While the three-minute thrill of loop-the-loops and heart-inmouth plunges is more than enough for most coaster enthusiasts, Rodriguez says he has taken the pastime to another level.
"I love the romance, adventure and sometimes danger of it. I like the idea of seeing it through with a team. The people I met and the technical operators were fantastic," he says.
To while away the time he read newspapers and wrote pun-filled postcards telling friends, "This summer break is having its ups and downs."
He thinks it will be some time before this record is broken and he is back to the dizzy heights of Blackpool's Big Dipper.
When that happens his lucky charm will once again be Charles Lindbergh's book The Spirit of St Louis, about his one-man flight across the Atlantic in 1927. The legendary aviator said the Coney Island roller-coaster was an even more thrilling ride.
"I don't want to draw too many comparisons with Lindbergh, but people said he was crazy at the time," he says.
