Dear opponent, I too believe that wearing a hat can keep you warm. I just want to have a lighthearted debate, so for the sake and spirit of the debate I will claim... ... ... Hats and caps CANNOT keep you warm on cold days.
That is quite true, but people argue that they do not offer any protection or warmth because there is usually no ear protection, no nose protection, nor any eye protection. It may be your choice to wear them, but that does not mean you can gleam any protection or warmth from wearing such items.
I would like to thank the competitor for this indubitably fun and lighthearted debate. Yes it may be a person's preference to wear such items, even though some argue that they do not offer any protection. I do believe that such items do offer such protection and have played the Devil's Advocate for a interesting debate. All I can say is... good game... or debate, but either way it's a good game.
