Now you are the real definition of stupidity. Because I have cornered you about the difference between SGR and trains and also made you aware that there are electric trucks, you have now changed gear to food. For your information I'm even eating right now 🤣🤣😂🤣.
Actually I found that you are among the least literate contributes in this thread, you just pick words and think you know anything about them. Right now you were talking about Physics yet you don't know a thing about it, heri mimi mwenye hakufanya physics know few things zenye hujui😂😂
