OK, so I've been living under a rock for the last 50 years. I notice that internet communications are shortened to a few letters. such as: lol. What does this mean? Is there a dictionary I could refer to that explains these abbreviations so that I could figure out what the heck y'all are talking about?

The radio in my workshop wouldn't turn on this morning. No big deal (I was thinking to myself), I'll just get a new one the next time I go to the Electronic store. I proceeded with the day's work, but I found it difficult to stay focused on the job. After 2 hours I couldn't stand it any more. I locked up the shop and went directly to the store and bought a radio. Now I'm Rockin' again and the work in my shop is progressing nicely. I never knew how important music was to me until now. Is there any hope for me?

When viewing a video from the internet, it will run about a minute and then stop for a minute (freeze-frame) then resume running about a minute, then stop... over and over again. It takes an hour to watch a 5 minute video. Doesn't matter what website I'm on. Can anyone explain what's happening here? Otherwise the computer works fine.

I've owned several riding mowers over the years,and all of them have one problem common to all of them. The tires go flat after a day or two.Every time I want to use it, I first have to air up the tires. I tried that tire "slime" sold at the auto parts store but that stuff doesn't hold up very long, I still have to air up each time. Are there any better tires to be had?
