It feels wonderful to get a nice night of sleep. I find that I sleep better in the wintertime as I get to bed before 10pm & seem to sleep better when I am in bed earlier. Summer is a different story altogether though, since we end up playing tunes or volleyball on the beach till around 11pm. The sunshine doesn\u2019t set till around 10pm or so in the summer, & by the time I get home it is well past 11pm or later & I don\u2019t get to bed till 1am most mornings, then even with the whole-house air purifier humming away as white noise, because I don\u2019t run my central Heating & A\/C system, I can still hear people partying at the bar beside me. I pretty much wake up around 8am no matter what time I fall asleep, so needless to say I don\u2019t sleep as well in the summer. My local contractor neighbor plays ball with myself and others & he has trouble waking up to go to the Heating & A\/C company at 8am each day in the summer. I may not play as much ball this summer time because my knees are getting worse, although I am sure I\u2019ll still sneak in a bit. My heating & cooling job requires a lot of knee bending when laboring on air duct or carrying some heating device up a few flights of stairs. So my knees are pretty important in my laboring life, & I use them when I am playing the djembe in my band. I am going to the local company now to grab a HEPA filter, see ya. <\/p>\n
