not to mention that possession of the ring stopped or greatly reduced aging. it is a point specifically mentioned at the beginning of the fellowship of the ring.
On the other hand, Bilbo leaves on his 111th birthday, a ripe age even for hobbits, and he often refers to himself as 'old'
Well,
@Don't panic, as we about about to share an ale elsewhere, I'll confine my remarks to suggesting that I would have far preferred to have shared a glass of wine or tankard of ale with Bilbo than with Frodo.
Re his age, I really think that this was JRR Tolkien's attempt to write a credible reason for excluding him.
I loved his insouciance, and I think his journey would have been an interesting one to read, - had Tolkien written it - even if it would have made him a sadder and wiser hobbit, but a hobbit who still retained his humour and humanity.
I don't want us to hijack this thread and turn it into a Tolkein thread. But I do tend to agree with you, I'm not a Frodo fan either, but it is what it is.
People discuss books in detail all of the time, so I doubt that this is an issue. And TLOTR is a classic, much read and much loved.
Personally, I see it as a superlative - and seminal - example of world building, epic in range and scope, an extraordinary and magisterial work, and with some stunning set pieces (Ents, Mines of Moria, Saruman, to name but three): However, it is not without its flaws, some of them serious, (complete inability to write credible female characters, Frodo, less of Sauron and what motivated him that I might have liked to have seen, Frodo & Samwise..)
