That was my thought also. Gates is only about 2 1/2 years older than me. I thought about how old I'll be in 2050 (92) and knowing Gates is older than me I wondered if he would be alive in 2050.
Regardless, the horrors the global warming supporters that they have been telling us about we're all supposed to have happened already. But the earth and sun just won't cooperate with their plans.
