As I get older, I lose interest in anything on TV except the news.

"As I ___, I also ___" When using this form, the two things that are happening should be progressing at approximately the same rate. However, when you say "As I get older", aging is something that progresses slowly and constantly, but when you say I lose interest in anything but news, that is something that can either be true or false. It is not something that makes sense as a progression. So, the first thing is a slow progression, but the second thing is a one time event.

In the sentence I edited, I changed "As I get older" to "As I have gotten older." "Have gotten" is no longer a statement of progress. It is a past event that is either true or false. So, now both things are happening at the same rate. I have gotten older at some time in the past, and at that time, I also have lost interest. Both are one-time, discrete events.
