Really cool or really gross?

I had an idea to collect a sample of hair at least once a year until I die. I think it'd be cool because over time i'd be able to see a fading rainbow that shows I was once young and remind me that I'm going to die. But then I'm thinking it would be gross because for most of the time it'd just be a dusty vile of hair I'd have to explain to any one who saw [where i hid] it. And I'm pretty sure no one would think it was cool so i'd always have to come up with stories about how I'm... iono... trying to see if over time they'd form one long strand? Or say I'm collecting samples for that clone I'm trying to grow and then absorb? That's no way to live. No. Not in the future. Maybe this isn't such a good idea...
