The gel in our eyes begins to shrink with age (and detach from the retina). As is the case with all things aging, it doesn't follow a set pattern. It happens early for some and late for others.
If you are seeing more floaters than you normally do, don't panic but do consider going for eye exam just to ensure that your retina is fine.
As for the floaters, my ophthalmologist gave me a long ass story about conscious attention, how he lived near a train track and with time he became immune to the disturbing sounds of trains passing by yada yada.. Point is you should become blind to the new ones with time :)
