Formula 1 fans turned to Twitter on Friday to support Michael Schumacher?s birthday and recovery. In an initiative by Lois Martin, F1 Fans Updates and Formula 1 extra, fans wore red coloured clothes on Schumacher?s birthday and uploaded their photos on Twitter with the hashtag #Red4Schumi. Sarah from F1 Fans Updates made a card(pictured above) of 170 fans around the world who directly supported the initiative. Thousands of others who couldn?t take part in this programme, simply sent their well wishes to Schumacher, who is currently in induced coma in Grenoble Hospital after a skiing accident last Sunday in the French Alps. According to the latest update from his management, he remains in stable but critical condition. We wish him a speedy recovery.
