Age, work and piercings

I'll be 30 soon enough. I have an office job. I have tattoos all over my mid section, you can't see them. But I've been wanting a piercing for a while now. Nose maybe, or center lip. You have to wear the jewelry until it heals and I don't want to get in trouble during that time. Idk what I could do about that really. I feel either too old or like it would get me in trouble at work.
