# Connected sum while keeping curvature bounded.

Is it possible to perform a connected sum of two Riemannian Manifolds or Orbifolds while keeping curvature bounded from below? More explicitly, If $M_1$ and $M_2$ are two Riemannian manifolds (or orbifolds) of (sectional or Ricci) curvature bounded from below, is it possible to obtain a Riemannian metric in $M_1\#M_2$ that also has curvature bounded below?
