One thing that I fear is hair loss. My hairline is receding a little bit... nothing you'd notice if I didn't spike my hair, but you could notice if you were looking for it. I'm not quite ready to lose my hair just yet. I like my hair. I guess it's probably time to start doing something about it.
Of course, if I just ignored it, think of the potential savings! Less hair glue, fewer haircuts, fewer bleachings. Cha-ching.
