If your saddle is higher than your handlebars - and you have little chance of becoming the object of a wistful missed connections entry if it isn't - you know neck strain.
On the long trip from your basement "loft" to attend class, pull espressos or occupy wherever, you will become a sort of super yogi, capable of holding a tendon- tearing position for hours on end.
The alternative, of being hypnotised by a spinning front wheel, is a pretty good way of testing the strength of your front wheel compared to the panel on the passenger door of a turning car.
BONUS TIP: Ride far enough like that and as you walk down the street, you will appear to forever be contemplating the clouds, unable to lower your eyes to human level. You need to swap to an upright dutch bike when the missed connections entries start overwhelmingly coming from your BFFs / parents/ housemates.
