[delicate trench]

part.touched:connect(hit) will always be ture it doesn't make sense as a condition

local Part = script.Parent

local function OnHit(hit)
local char = hit.Parent
local hum = char:FindFirstChild("Humanoid")

if hum then
hum.Health = 0
    end

Part.Touched:Connect(OnHit)

Oh what it returns a boolean? Isnt it an event

[spiral roost]

It returns a connection to be disconnected later

local connection = part.Toucher:Connect(OnTouch)

task.delay(10, function()
  -- disconnects the function OnTouch from the touch event after 10 seconds
  connection:Disconnect()
end)

Oh i see

Something for memory leak

[spiral roost]

Not really

Yes but the main thing is for example when you don't want to detect touch anymore
