It's quite interesting this one...
...and I happen to have the full data from HESA on my desk: women absolutely dominate law degrees.

But I also work with law firms as clients: almost 50% of them will quit the law before reaching 30.

Law is still, alas, an incredibly macho profession, and most ladies simply have too much sense to stay in it. Am 31 now, and the only one of my female friends from uni still sticking with the law explains to me every time she sees me why she's about to quit.
