Hi, please help me with understanding some usages.
1. Used to
Is it grammatically correct to use it in present or not? like I am used to painting. I am used to it. I am getting used to late sittings. I am used to jogging. or for future use?

2. Lest and Would that
Are these obsoleted to use nowadays?
1) Yes, your examples are all correct.
2) Would that is not usually used today. Lest is heard occasionally, but is used much less than it once was.
Is usage of "As if" obsoleted or not? and is it used in all present, past and future tenses? please tell me
