LOOK AT THE DATE!

Do responses lose their validity because the question is old?
There's this wonderful thing called a search engine that will turn
up all sorts of information -- questions, replies, etc. -- regardless
of when they were stated!

Responses lose something.
In fact, they're not responses after all that time.

Do "chemical antidotes to bleach" change? If someone was looking
for that information *today*, would the response be different?
If someone was CASUALLY READING the bits of this thread, would they
say, "Gee! I didn't know that! Oh, wait... the original thread is
20 years old so I should ignore *today's* reply as it probably isn't
valid..."?

Using the old thread may or may not be a good idea.
If I was following up on something I knew to be a few
years old, I'd be sure to mention it.
