Well, yes you need to indicate you have applied before and, in fact, having previously withdrawn an application has been grounds for non-routine processing and/or RQ in the past.
I think there might not be any non-routine processing and RQ if I meet the requirement of residence cause I am over 55 year old now.

Where are you getting that from? Anyone can get non-routine processing and at one time having previously withdrawn an application was a potential risk factor for non-routine processing and a possible RQ on your next application. Is that still the case? Nobody konws.
