Stop holding on to "your 20's" like it's a thing. They are not things, years.
You're 3. You've been 2 for ten years. I'm 4. I was 3 since you were 2. In 10 years I'll be 5 and you'll be 4.
I'm only a year older than you.
You're 3 and you're going to live to at least 20 and I am going to live to at least 21.
Toss the terrible 2s. Toss the numbers. Toss your number.
