I am wondering how do one provide a "reasonable explanation for lack of extracurriculars"
.. Honestly, i have been too busy at work to find time for other things. I think it is too late to try to do some extra-curricular work. thanks for your suggestions.
I don't think you have to provide an explanation. If you've been too busy for other extracurriculars, that'll be evident to the AdCom when they review your application, essays, resume, and recos.
The other elements of your application should say more than enough about who you are and why you'd be a good member of the NYU community.
