Suit yourself.
Understanding quantities is key. For example, we all know your relative mass increases with velocity: that is the principle. Without the quantity, you may not realize it is not significant until you get really fast.
How fast? Moving from zero to 95 million mph gives a relative mass increase of about 1%. So now you think the principle is millions of mph faster is relatively a small impact.
But not so fast, pardon the pun. When your velocity makes your relativistic mass 1 million times your rest mass, an increase of 1 foot per hour in velocity increases your relativistic mass 52%.
