I didn't stay up, nor did I set the alarm, because I always wake several times in the night and rarely get more than 2 hours sleep together. Went to bed at midnight, thought 'I'll be awake by 1.30, probably again at 3.00 so that's all right'. I woke up at 5.34. Almost unheard of. 
Retiring and living frugally in money from downsizing after years of stress




but agree about the 3D effect.
