The disaster also had a long-lasting effect on the fans. Christopher Hammond, who was 12 on the day, said on the 20th anniversary of the fire: "As a 12-year-old, it was easy to move on – I didn't realise how serious it was until I looked at the press coverage over the next few days. But looking back and seeing how much it really affected my dad makes me realise what we went through." His father Tony went back the following day and said: "I wondered how anybody had got out alive, but I also began to feel guilty that I had got out when so many hadn't." He had to undergo counselling and was unable to go to another game for several years. Matthew Wildman was 17 at the time and needed crutches to walk because of rheumatoid arthritis. He was helped out of the stand by other fans and spent a period of time in hospital. He later said: "I have never known anything like it, either before, or since. Everybody in the city was devastated, but there was an amazing number of volunteers. [...] I still have terrible memories of the day, but it is the humanity of those that helped us that I reflect on."
