Hobbit age?

[The Might]

Ok, so my question is pretty simple.
Did the Hobbits tend to live longer or less then in the past during the War of the Ring?
I mean, as far as Elves are concerned, age is not very important.
For Men, especially those of Numenorean descent or from the line of Dol Amroth, the life expentancy is clearly higher then in the case of other men, but still decreasing.
The Dwarves seem to have a pretty constant life expentancy as well, with some examples such as Dain II who lived more then usual.
But what of Hobbits?
Bilbo clearly is out of question, since only the Ring led to his great age. But the Old Took is a good example of a Hobbit reaching a venerable age.
I would find it logical that their lifespan should increase, considering their good living conditions, but I don't really know.
I'm eager to see your answers.
