Is age just a number? “No” is what the common answer tends to be. On the surface that may be correct, as there are things that just naturally come with age such as physiological growth and general life experience within the laws of society (i.e. alcohol consumption and consensual sex). However, knowledge, wisdom and alternative types of experience can be learned at your will.
See, time is a relative concept and your age may depend on how you’ve used time.
