<human>: I've been playing rugby for a men's club in my area for the last 6-7 years. I've been involved on the executive board for the bulk of that time, and have progressed to become on of the more reliable players. 

Over the last couple of seasons, I've been thinking about retiring. I have some back issues that can make playing tough, the time commitment can be very demanding, and my heart isn't in it the way it used to be. I'm on the wrong side of thirty now, and am concerned about/losing patience with the various injuries that come with playing.

The main thing holding me back is the fact that that club is on hard times, and I feel guilty about 'abandoning ship.' I've been training hard in preparation for this season, and I feel like I'll be leaving a void behind if I quit or take a break.

At the very least, I'd like to take a break for a season and see whether my body starts feeling better or whether I really miss the game and want to come back. My questions are: Is this reasonable? Should I feel guilty about possibly letting my teammates down? What is the best way to approach this with the team?

Can you give me the gist of the text in a nutshell?
