Any reason NOT to slap the 'synchronized' keyword everywhere?

synchronization

In my java project, almost every non-static method I've written is synchronized. I've decided to fix up some code today, by removing most of the synchronized keywords. Right there I created several threading issues that took quite a while to fix, with no increase in performance. In the end I reverted everything.

I don't see anyone else writing code with "synchronized" everywhere. So is there any reason I shouldn't have "synchronized" everywhere?

What if I don't care too much about performance (ie. the method isn't called more than once every few seconds)?
