The most natural solution for most people is to give shards of your key to various friends/family that you trust not to collude and reconstitute your key (or be socially engineered -- make them talk with you on video chat or something). Require 5 out of the 9 shards to reconstitute it.
Obviously you can scale up your security according to the value of your account and your threat model.
