I don't think I have ever reached a point where I cannot hold on any longer. So my answer would be that I simply don't know.
Why have I not attempted to find out? Well, it's not like drugs where actually doing it causes some harm - thus encouraging me to find the limit. It's more like being offered free money each day and have the option to take it or leave it. I mean, why would I not take the money?
