There are various pronunciations, though.

North American English, for example, has the following pronunciation variations:

20, twen[ti:], twen[ni:]
30, thir[ti:], thir[di:]
40, for[ti:], for[di:]
50, fif[ti:], fif[di:]
60, six[ti:], six[di:]
70, seven[ti:], seven[di:], seven+[ni:]
80, eigh[ti:], eigh[di:]
90, nin[ti:], nin[di:]

Also, I'm not convinced that a glottal stop takes less effort to produce than a /t/.

Raymott, you're absolutely right. As I was typing "sheer laziness", it struck me that it may not be the reason behind it, but I couldn't think of anything more appropriate!

Ah yes, something becoming "sumfink". That used to drive me mad at school!

i am truly sry because you might think my question ridiculous but i've been confused about this for awhile

In the word "twenty" the second t sound is often left out by native speakers when speaking quickly. This is called t deletion, which happens with some degree of frequency in ordinary conversational English. The t sound is often left out by native speakers when it comes after "n". Another example is the word "mountain". If you haven't already, take a look here: T sound in American English.

As for the word "thirties", we pronounce the second t.
