Are there any countries in the world where it is ever really hot or reall cold and where the ambient temperature stays roughly the same ?

They would be roasting hot or Frezzing cold though....
is there anywhere in the world where the temperature stays at around 70 degrees fahrenheit ?      

Did you intend to say "never" in your question instead of "ever?"

Yes....my eye pad does terrible spelling mistakes to make me look stewpid ....it's me own fort four not s asking it two bits when I first got it...:(

I was up early one morning about 20 years ago and for some incomprehensible (in retrospect) reason I relied on the spell check function in Microsoft Word and then didn't proofread what I had written before I printed it.

.....NEVER again.

I'm sure most of mine are ok until the second i push send.....looking at my first reply to you its changes "smashing" to "s asking" ....I think my Ipad hates me....
 Yes I do proof read things and yet it still manages to happen.....often as I type some ,letters take a second or two to appear ...  then it goes crazy and prints a hole line.......

i think ink its trying to teach itself to speak blonde..... :( 

An impossible task if you've not been born one...:)
