“This is tough, but it also depends a little bit on how the season has gone and how the car has gone,” Alonso told DAZN at the season finale.
“If you have a McLaren, a Ferrari or a Mercedes it's much less hard because the car doesn't jump, the car goes fast.
“If you have our car from Brazil, you injure your shoulder and you have four races injured."
At 43 years old, Alonso is the oldest driver on the grid, but the Aston Martin star is adamant that is not a factor.
“You take a pill to get rid of the pain and that's it, and it has nothing to do with age," he explained.
"Because people quickly, if I'm physically bad, they think I'm 43 years old.
“The other day, in the closed park, it was like The Walking Dead, they [other F1 drivers] were all on the ground, and I'm pretty good, much more in one piece than them, so it's a little bit of the little injuries that you have.”
