Jay,

Again, lovely idea here. I think I counted 19 syllables, though and haiku must be no more than 17.
What about:
stiff and creaking joints
nature's warning you, "watch your
steps, here comes the fall."

By taking out the "way of" takes it to 17, I think. Just an idea - play around with it....you're almost there!
All the very best

Hi Jay,

This needs a little tweaking as it now has too many syllables on the second line and also the third line should be a statement all on its own, a real twist. The title is great, needs no work. I fooled around a little with the words, see what you think:

Stiff and creaking joints--
Nature's way of warning you.
"Beware of the Fall"

Take care,
Ingrid

You actually have really good ideas with your haiku, so once you get the syllable count correct, they will be excellent!
All the best
