Always best to start with something small.

Now that is a strong argument that the salicylic acid had no real effect, and that all three went away when your immune system figured out how to combat the virus. I believe the research has shown that most wart removal techniques, including surgery, are no more effective than waiting for it to go away. I think the theory is that eventually your body figures out how to kill the virus but until then, all of the above techniques are of limited value because unless you excise the wart with huge margins, you are still likely to have infected cells ready to begin multiplying again.

The math here is not remotely correct. For one thing, the plumber is not taxed on his income but upon his profits. In fact, typical net margins for businesses are in the 2-8% range, meaning the portion of cost due to tax is as much as 50x lower than you state.

Sadly, the answer is probably "both". If the network is really shoddy, it would be best to fix it. But if the files are "mission critical", then it is worth your time to use a reliable transport even if the network is solid. If three things have to break (network, TCP, plus transport) it will always be more reliable than if only one or two things need go wrong to jeopardize your system. Plus, if you don't validate your data, the kinds of errors that causes can often be really bad, much worse in some cases than something just failing outright.

I think AC has the only correct response to this post. All of the people talking about CRs must not have any experience using FTP over a spotty connection, because it is quite common to run into these kinds of issues, especially on lengthy transfers.
