How do I locate a part/model or something else if it keeps changing name?

Lets suppose I have a part in a model and I want that when you touch that part the parent of the part(model) will change name to the age of the player who touched it .

Now lets suppose I have a script which locates the model and after that it changes its name to the player's acc age who touched the brick.

Lets say the model's name after it has been touched is "100 days old"'

How do I locate the model? Cause the model can be a name is an age I do not know.

I Recommend That You Make It In A Model With A Specific Name In The Workspace For Example "Name_Changing_Brick", You Would Then Do A Script With The Following:

game.workspace.Name_Changing_Brick:GetAllChildren()
local plr = game.players.LocalPlayer
local sg = instance.new("ScreenGui")
sg.Parent = plr.PlayerGui

local fr = instance.new("Frame")
fr.Parent = sg
fr.BackgroundTransparency = 0.4
fr.BackgroundColor3 = Color3.FromRBG (4, 33, 61)
fr.Name = "OutputBackground"
fr.size = {0, 356},{0, 161}
fr,Position = {0.661, 0},{0, 0}

local tl = Instance.new("TextLabel")
tl.Parent = fr
tl.BackgroundTransparency = 1
tl.TextColor3 = Color3.FromRBG (255, 255, 255)
tl.Position = {0, 0},{0, 0}
tl.TextSize = 26
tl.Text = "Name Changing Brick Is Now Known As:"

local tl2 = Intance.new("TextLabel")
tl2.Parent = fr
tl2.BackgroundTransparency = 1
tl2.TextColor3 = Color3.FromRBG (255, 255, 255)
tl2.Position = {0, 0},{0.509, 0}
tl2.TextSize = 26
tl2.Text = game.workspace.Name_Changing_Brick.Child.Name

end
