I thought this is worth a mention
I finally finished this bottle of hair gel

what's so interesting you may ask
well, this bottle lasted me 4 years
actually, not really, cos the last bit, I find that it smells funny, thus I decided to stop using

yes, I'm not sure if others would have used their hair gel for 4 years or more

oh ya, I have short hair plus 1 year botak in NS
maybe that explains it
