In the talk I would like to discuss some statements and questions about convex subsets and convex hulls in generic Riemannian manifolds of dimension at least 3. The statements, obtained jointly with Anton Petrunin, are elementary but somewhat surprising for the Euclidean intuition. For instance, the convex hull of any finite non-collinearset turns out to be either the whole manifold or non-closed.
