MiT's second short essay: "Although you may not yet know what you want to major in, which department or program at MIT appeals to you and why? (100 words or fewer)"
Someone who I consider very influential in my life, who I played multiple sports with and learned from currently attends MiT. Would it be inappropriate to mention them? I wouldn't mention their name or anything more specific than that they've published research in the department that most appeals to me, that I would take advantage of the opportunity to learn from peers like them, etc.
