*sigh*
Your attitude is so... childish...
Anyway might as well reply before i sleep.
You don't have to take damage to become weaker. Him being over 900 anyway, he was old and weak compared to what he could be. Anyway, if you're old and in fight, say your an old man and you fight someone, even if you don't get hurt, the fight itself tires you out, and this can effect your body more in the long run. Yody fought on par with dooku, then he stopped that pillar falling which looked like it strained him alot. When you're old that can effect you in the long run. This is what i'm saying.
You say he was a master in control, but i think i remember, when all the jedi were dying, he dropped his staff and reached for his heart?(or something like this) You could tell it was hurting him.
And yes this is still a film.
I thought you posted this for a discussion but you don't seem very open about it.
..... The childish comment was not needed. Try posting more detailed responses, like you just did, the first time rather than leaving your arguments really basic and open for improper interpretation....
Anyhow, you make a good point that an old person could be affected significantly even if they don't take any actual damage, but my point was that Yoda did not show any long term difference after the battle when compared to before it.
Yoda always walked with a hunched back and somewhat crippled step. The battle with Dooku resulted in no significant difference in his walking capability. Other than that, its hard to say whether or not he actually suffered any other long term damage from the battle. My point about him being old is that he is sooo old, that its likely he is so stoic that 1 battle, no matter how severe, would not likely effect him as much as you would think in terms of a normal old person. My whole point was that he was no ordinary old person, clearly.
And the bit about him suffering from the deaths, I know he suffered a lot, he clearly showed signs comparable to a minor heart attack. But that was mostly
emotional and psychological pain, a result of him being so interconnected with all life around him. Now you could easily say that this could be a significant reason that he got weaker as a result.... but don't forget that Yoda was also a master of dealing with this kind of loss.
I mean he basically founded the entire Jedi order as we know it, and the number one rule is that attachment is a weakness and that whenever someone close to you dies, you do not grieve. Rather, you rejoice at them becoming part of the force. For this reason, I could conclude that Yoda is absolutely the best at realizing this loss and putting it behind him for the better. By this, I'm implying that this would not cause him to become any weaker in the long run, when compared to his fighting capability.
Despite all this, I still feel that Yoda should have been able to absorb Sidious' lighting if he was aware he could use it. Because no matter how much theoretical damage Yoda suffered prior to that, he should have still have had his sense of preparation and concentration imo, when it came to battle, that he always had.
