Myasthenia (my-from Greek Î¼ÏÎ¿ meaning muscle + -asthenia á¼ÏÎ¸Î­Î½ÎµÎ¹Î± meaning weakness), or simply muscle weakness, is a lack of muscle strength. The causes are many and can be divided into conditions that have either true or perceived muscle weakness.

It occurs in neuromuscular diseases, such as myasthenia gravis.

I was at the New England Woodworking Show last week not really looking for anything in particular when I happened on the new Bosch Miter Saw. I had looked at the Festoolâ¦ too expensive and I hate that your blades are limited by the size of the arbor & that Festool wants you to buy their blades. I started really looking at the Bosch and the price was so good ($694 show price) that I ended up ordering one the next day.
