Addressing what it is like to still be competing at 40, the Alfa Romeo driver said: "I'm sure it's not like it was when we were in our 20s.
"But I think generally the whole sport has changed a lot since those days, and this year has been pretty easy because we haven't done any races except one.
"I wouldn't say the training has changed. If anything, it's probably less because when you're comparing to almost 20 years ago - probably as the training goes, everybody's a bit smarter as to what needs to be done, what not to do, what is helpful and what can actually be harmful.
