Darren goes to a monster truck rally. Before going to the rally, he does not read the back of his ticket, which states "Monster truck rallies are extremely loud and noisy. Ear protection is highly recommended. By purchasing this ticket, the bearer of the ticket has expressly assumed any and all risk of ear injury associated with attending this event." Darren, not having read the back of the ticket, does not bring earplugs or other protective ear equipment to the rally. After the rally, he has constant ringing in his ears and cannot clearly hear people talk to him. Did Darren expressly assume the risk of ear injury? What about impliedly? Why or why not?
