我不希望 fancyheader 以粗體顯示運行標題

Question

我正在使用下面的程式碼，它給出了運行標題大膽的字體。

但我想要正常的字體。

\documentclass[11pt,letterpaper, twoside]{article}
\usepackage[english]{babel}
\usepackage[margin=1in,footskip=0.25in]{geometry}
\usepackage{amsmath,amssymb,authblk,eurosym,fancyhdr,float,footmisc,graphics,graphicx,pdflscape,pslatex,rotating,setspace,subfig,tabularx,url,xargs} 
\usepackage[pdftex,dvipsnames]{xcolor}  %

\title{Your Paper}
\author{You}

\begin{document}
\maketitle
\begin{abstract}
Your abstract.
\end{abstract}
\clearpage
\pagestyle{fancy}
\fancyhead{} % clear all header fields
\fancyhead[RO]{\textbf{Header text}}
\fancyhead[LE]{\textbf{Tom \& Jerry}}
\renewcommand{\headrulewidth}{0pt}
