Here's a series of approximations of what I do. Feel free to stop reading at any point if it makes you feel uncomfortable.

2nd approximation: I work in topology
3rd approximation: More precisely, low dimensional topology
4th approximation: I mainly care about smooth, 4-dimensional manifolds and everything that comes with the territory
