Lifetime membership question

I have a long way to go, but had a question about lifetime membership.

If I attain it, by getting my 1,000 points, can it ever be lost under any circumstance?

What about if I "gift away" some of the points that were used to get me to 1,000. Let's say I reach 1,000, then gift a helpful post author 5 points, does that mean I need to get another 5 to "re-acquire" my lifetime status?

Wasn't sure, so thought I'd ask. Thanks!
