Post wisdom teeth surgery? Foods?

I had my wisdom teeth out which would be 2 weeks ago tomorrow. Is it okay to eat spicy foods now? Nachos? I don't have as much pain as I use to. I'm only taking Advil if needed. Which I didn't take anything yesterday. I'm able to eat more meals just I haven't ate anything too hard. I still have the holes in my mouth from getting the teeth out. I'm kind of afraid of getting dry sockets. Is that still possible being that it has been 2 weeks? I'm just still taking cautious about what I eat cause I don't want to jab anything back there in the holes.

Why do people say that Khan and Haye have gl chins?

Wlad does have a gl chin, as does Khan. Both were evidenced in the ring. David Haye is more of a sticky wicket in that yes, he was knocked out by a light heavyweight, but Haye was also seriously ged out. Haye used up all his anaerobic energy while chasing a KO. That's more of a loss due to a tactical error rather than gl jaw. I don't think Haye is all that rugged, but we haven't seen any evidence of "easy to knock out-edness" at heavyweight.
