Could you check the sentence and correct my mistakes?

I like reading books while TV’s on.

I am normally hearing the TV while my eyes are on the book, and watch TV only when I find the scene is really interesting and worse to watch it.

I believe this way of spending time saves some of mine, for instance, when I want to do excise, rent DVD and need some shopping, I just walk up to the rental shop and do the shopping on the way home.

However, I got headache by doing that today, also not sure if that is really effective, might loosing some concentration.

My try:

I like reading books while the TV’s on.

I am normally hearing the listen to the TV while my eyes are on the book, and watch TV it only when I find the scene is program(s)/ broadcast really interesting and worse worth to watch it.

I believe this way of spending time saves some of mine my free time ( I hope this is what you are trying to say) , for instance, when I want to do some exercise, rent a DVD and need some shopping, I just walk up to the rental shop and do the shopping on the my way home.

However, I got a headache by doing all these today, also I am not sure if that it is really effective. I might be losing some my concentration.
worth watching
. For instance, today
today; also I

Thanks Feebs 11. I don't rememver where I saw but I read somewhere that "to" can be used after "worth". Is it a rule valid for something else or do I completely make it up?
I have never met that usage - perhaps you have confused it with something else?
Perhaps you're thinking of "worth it to do something"

Hmm, probably.
