Thought you hated History? What's with events and sequence of events and the numbering in years etc.? Drives you crazy, no?
Biology is worst. If you are into genes and its function in signaling pathways, you will need to pull your hair. Let me explain..
In history, a historical person such as Napoleon is none other than Napoleon. In Biology, a gene can have shitty lot of aliases and these names were amended several times in history. Try searching in the archive for a gene and it will kill you prematurely because you will "vomit blood" (due to extreme trauma to the heart). Also, you have Napoleon 1, 2, 3, 4 and a hell lot more that is involved in different aspect of event. They are cousins that are expressed in different spatiotemporal fashion and they might co-mingle at a niche. Confused?
It doesn't end. A gene in an event interacts with other genes, and each of the latter genes has its own aliases, cousins, twins etc.. Worst, each of the above genes has a function (or functional classification) and these too are historically amended. Imagine calling Napoleon as a Commander (analogy to function) in a period and then calling him again as Napoleon the "killer". In Biology, you also cluster genes together and then de-cluster them or overhaul the entire classification. The list is so long....
The ultimate worst scenario of all is that, there are gazillion historians (biologists) writing accounts of their studies. Your head will explode going through all these accounts, or venturing into unfamiliar territory...
Bioinformatics helped, but not enough. Google helped but not good enough. That's because gene acronyms sometimes clashes and bring hell to the reader.
So, Biology is fun if you are into history and have the knack and liking in decoding...
